Lawmakers Demand Action on 7-Eleven and Circle K Overcharges

Five US House members are demanding action against 7-Eleven and Circle K after a Guardian investigation found the two largest convenience store chains in the United States routinely charge customers more at the register or pump than the prices advertised on shelves and outdoor fuel signs.

The lawmakers said the pricing practices at the two chains underscore the affordability struggles facing everyday Americans, according to a report published by the Guardian on October 3, 2026.

The Guardian's investigation, published September 24, 2026, documented that customers frequently pay more for snacks, gas and other items than the prices the stores promise on the shelf or on fuel signs outside. The discrepancies appear at both chains, which together operate the largest convenience store networks in the country.

"It's enraging," one lawmaker said, describing the response to the findings on Capitol Hill.

The congressional response signals mounting political pressure on the convenience store sector over pricing integrity. The five House members argue that when shelf tags and pump signs do not match the final charge, consumers — particularly those in low-income neighborhoods who rely on corner stores — bear the cost.

The Guardian's findings cover both in-store purchases and fuel sales, two of the highest-volume transaction categories at convenience stores. Overcharges on gasoline carry particular weight, since advertised pump prices are the primary basis on which drivers choose where to fill up.

7-Eleven and Circle K are the two largest convenience store chains in the US by store count, giving the alleged pricing gaps a broad national footprint. The House members say the practices documented in the investigation reflect a wider pattern of affordability strain on American households, an issue that has dominated political debate ahead of the midterm cycle.

For the chains, the congressional attention raises the prospect of regulatory scrutiny and potential legislative action on pricing accuracy at the point of sale. How 7-Eleven and Circle K respond to the lawmakers' calls — and whether federal or state authorities open formal inquiries into scanner and pump pricing practices — will shape the next phase of a dispute now moving from newsroom findings to Capitol Hill.
