Consumer Daily Reports

A Georgia Techled team will examine how recommendation algorithms shape young users behavior.

By Mark Huffman Consumer News: Researchers launch major study into TikTok algorithm’s impact on teens of ConsumerAffairs
March 4, 2026
  • Meta CEO Mark Zuckerberg testified in Los Angeles County Superior Court last week, defending his company against claims that social media harms children.

  • A 20-year-old plaintiff alleges Instagram and other platforms are intentionally designed to addict young users.

  • A new Georgia Tech study aims to examine whether TikToks recommendation algorithm contributes to unhealthy patterns among adolescents.


As legal battles intensify over whether social media platforms are engineered to hook young users, new academic research is seeking to shed light on how recommendation algorithms shape teen behavior and mental health.

Munmun De Choudhury, a professor in Georgia Techs School of Interactive Computing, is leading a multi-institutional team that will audit TikToks recommendation algorithm using data from more than 10,000 adolescent users. The four-year project is supported by a $1.7 million grant from the Huo Family Foundation.

Big trial in the background

The study comes amid growing scrutiny of social media companies. In Los Angeles County Superior Court last week, Meta CEO Mark Zuckerberg took the witness stand to defend his company against allegations that platforms like Instagram are designed to foster addiction among young users. Critics argue that algorithm-driven feeds play a central role in keeping teens scrolling for hours at a time.

De Choudhurys team hopes to better understand what young people are actually exposed to when using TikTok and how those exposures may affect their well-being.

We hope to learn the different types of negative exposures that young people experience when using TikTok, De Choudhury said. This can help us characterize what theyre watching and build computational methods to understand the consumption behaviors of these participants and how theyre affected by the algorithm.

The project is a collaboration with Amy Orben, a professor at the University of Cambridge, and Homa Hosseinmardi, an assistant professor at UCLA.

Major hurdle

One major hurdle for researchers has been limited access to social media data. Platforms have tightened restrictions on their application programming interfaces (APIs), making it difficult for outside researchers to study user behavior at scale.

We cant do the type of studies we did 10 years ago with X (formerly Twitter) because the API is much more restrictive, De Choudhury said. There are limited ways to programmatically access peoples data now.

Instead, the team is relying on data voluntarily shared by young participants. Orben collected TikTok archives from more than 10,000 adolescents in the United Kingdom who consented to provide their personal data in compliance with the European Unions General Data Protection Regulation (GDPR).

Unlike many prior social media studies that focus on what users post publicly, this research includes watch histories offering a rare window into passive consumption.

We dont understand passive social media consumption very well, so we hope to close that gap and learn what that looks like, De Choudhury said. Is what theyre consuming directly related to what theyre posting? How does passive consumption affect young peoples mental health?

Researchers believe the findings could eventually inform design changes aimed at reducing harmful effects. Adolescence is a particularly important period, De Choudhury noted, because early signs of mental health conditions often emerge during these years.

Consumer News: Costco tweaks its iconic $1.50 hot dog combo for first time in decades
Thu, 30 Apr 2026 19:07:07 +0000

Costco adds a healthier option to its classic meal

By Kyle James of ConsumerAffairs
April 30, 2026
  • Costco is making its first real change in decades to its iconic $1.50 hot dog combo, one of the most well-known deals in retail.

  • Shoppers now have the option to swap the traditional soda for a Kirkland Signature bottled water at no additional cost.

  • The update reflects shifting consumer habits, but the core value of the deal and its $1.50 price remains unchanged.


For decades, Costcos $1.50 hot dog and soda combo has been one of the most untouchable deals in retail. Prices have gone up everywhere, from groceries to gas, but that combo has stayed exactly the same.

Now, for the first time in more than 40 years, Costco is making a small but noticeable change.

Shoppers can now choose a 16.9-ounce bottle of Kirkland Signature water instead of a fountain soda. The price stays the same, and the original soda option (with free refills) isnt going anywhere.

On the surface, its a minor tweak. But its also a signal of how consumer habits are shifting and how to make smarter choices when youre at Costco.

Whats actually changing (and whats not)

The core deal remains untouched:

  • $1.50 still gets you a hot dog + drink.
  • Soda with free refills is still available.
  • No price increase (and leadership says its staying that way).

The only difference:

  • You now have a healthier, more convenient drink option.

That may not sound like much, but for regular Costco shoppers, it removes a common friction pointespecially for people trying to cut back on soda.

Why this matters for shoppers

This change isnt really about the hot dog, its more about changing consumer behavior.

More shoppers are:

  • Cutting back on sugary drinks
  • Looking for simpler, cleaner options
  • Trying to avoid waste (grabbing a soda cup they wont use)

And Costco is adjusting without touching the price.

This translates into you getting more flexibility without losing value.

How to actually use this change to your advantage

If youre grabbing a quick meal at Costco, this is one of the easiest ways to make a healthier choice without spending more.

Heres how to play it:

  • Choose water if you wouldnt drink the soda:A lot of people grab the combo and skip the drink. Now youre getting something youll actually use.
  • Stick with soda if you want max value:Free refills still make soda the better pure value play if youre staying in-store.
  • Use it as a budget meal strategy:The combo is still one of the cheapest prepared meals anywhere, especially when compared to other fast food spots.

The bigger takeaway

I realize this change is small, but it highlights something bigger.

Costco rarely touches its core value items like the hot dog meal or rotisserie chicken, but when it does, its usually to:

  • Improve overall flexibility
  • Match changing customer habits
  • Keep shoppers loyal without raising prices

And right now, with food prices still so darn high, that matters.

Consumer News: Maryland bans surveillance pricing in grocery stores
Thu, 30 Apr 2026 19:07:07 +0000

Will other states take the same action?

By Mark Huffman of ConsumerAffairs
April 30, 2026
  • Maryland has become the first state to ban surveillance pricing in grocery stores.

  • The new law targets the use of personal data to set individualized prices.

  • Supporters say it protects consumers, while retailers warn of unintended consequences.


Maryland is breaking new ground on consumer protection, becoming the first state in the nation to prohibit so-called surveillance pricing in grocery stores a practice that uses shoppers personal data to charge some consumers higher prices than others.

Gov. Wes Moore signed the legislation into law this week, marking a significant shift in how retailers can use customer information. The measure bans grocery stores from adjusting prices based on data, such as a shoppers purchase history, location, income level, or online behavior.

Supporters say the move is designed to ensure transparency and fairness at a time when digital tools are increasingly shaping the shopping experience.

What is surveillance pricing?

Surveillance pricing refers to the use of algorithms and consumer data to set different prices for different shoppers, even for the same item. While retailers have long used loyalty programs and coupons to offer discounts, critics argue that newer technologies could allow companies to quietly charge higher prices to certain customers based on what they are willing or able to pay.

Maryland lawmakers said the practice raises concerns about privacy and potential discrimination.

"People deserve to know what price is on the shelf, and the price on the shelf is exactly the price they are going to pay at the checkout," Moore said at the signing ceremony.

"People deserve to know that the price that they pay is not different (from) the customer who walked in just before them, or different from the customer who walked in right after them. People deserve to know that their data will not be used against them to charge them more."

What the law does

The new law prohibits grocery retailers from using personal data to determine individualized pricing in-store or online. It does not ban traditional sales, coupons, or loyalty rewards programs, as long as those discounts are applied uniformly and transparently.

Retailers are still allowed to collect customer data, but they cannot use it to set different base prices for identical products.

Violations could result in fines and enforcement actions by the states consumer protection office.

Industry concerns

Retail groups have raised concerns about how the law could affect innovation and pricing strategies. Some argue that data-driven pricing can help stores manage inventory, reduce waste and offer targeted discounts to shoppers.

They also warn that broadly restricting data use could limit personalized deals that many consumers value.

Consumer advocates say the risks outweigh the benefits, especially if shoppers are unaware that prices may vary based on their personal profiles.

A potential model for other states

Marylands law comes as policymakers across the country take a closer look at how companies use consumer data. While dynamic pricing is common in industries like travel and ride-sharing, its expansion into everyday essentials like groceries has drawn increased scrutiny.

Advocates say other states may follow Marylands lead if concerns about fairness and transparency continue to grow.

Consumer News: Oil prices are surging and so are prices at the pump
Thu, 30 Apr 2026 19:07:07 +0000

The price of regular gas is up 27 cents in recent days

By Mark Huffman of ConsumerAffairs
April 30, 2026
  • Oil prices are rising due to the Strait of Hormuz disruption during the Iran war, limiting global crude supply and pushing gasoline prices higher.

  • U.S. gas prices have jumped 27 cents in a week to a $4.30 national average, with much higher prices in some states like California ($6.01).

  • Experts warn prices could keep climbing and remain volatile as geopolitical tensions persist and energy markets react to ongoing uncertainty.


As the Strait of Hormuz remains blocked due to the Iran War, millions of barrels of Persian Gulf crude remain in lockdown. Thats driving up the global price of oil, which in turn continues to push gasoline prices higher.

The price of Brent crude oil hit $126 a barrel this week before drifting slightly lower. WTI crude, produced in the U.S., rose to $106 a barrel. Thats having a big impact on U.S. gasoline prices, which have remained volatile since the start of the war with Iran.

Average gasoline prices rose in 39 states over the last week, with the national average moving higher, while diesel prices declined in most states, offering a brief divergence at the pump, said Patrick De Haan, head of petroleum analysis at GasBuddy, writing in the GasBuddy blog.

However, that divergence may prove short-lived. Oil prices have been climbing again as markets react to renewed geopolitical tensions and the cancellation of talks between the U.S. and Iran. As a result, gasoline prices are set to rise further this week, with diesel expected to follow. Many inland states including those in the Great Lakes and Plains could see average gas prices climb to their highest levels since 2022, while price-cycling markets may also experience another round of hikes in the next few days.

Increasingly expensive fuel

According to AAA, the national average price of regular gas today is $4.30 a gallon. Thats a seven-cent increase since Wednesday and a 27-cent increase over the last week.

While $4.30 a gallon is the average, motorists in many states are paying much higher. The average price in California is $6.01 a gallon, the highest in the nation.

Motorists in Mississippi are getting the biggest break, paying only $3.77 a gallon. But a year ago, the average price was $2.67 a gallon.

Looking ahead, GasBuddy expects continued volatility in energy prices. With negotiations stalled and restrictions still in place, the energy data firm says markets will continue to react quickly to any signs of escalation or renewed diplomatic efforts.

The persistence of supply-side risks particularly in key transit routes and export infrastructure suggests oil prices could remain supported in the near term, even as sentiment shifts rapidly with each new headline, the company said.
