Convenience stores' losses from shoplifting tripled last year to hit a record high, according to the industry.
The Association of Convenience Stores (ACS) came up with a total of £131m, based on estimates from 7,123 shops in England, Scotland and Wales.
The findings, seen by BBC Radio 4's You and Yours, show an average annual loss per store of £2,605.
Retailers say the police response is inadequate, with one store owner installing bicycle chains on fridges.
"It is possible that some companies have previously underestimated theft levels in their business," the ACS admitted to the BBC.
