Daily deals site Groupon has suspended all gun-related promotions, according to a report by AOL Daily Finance.

“All scheduled and current gun-related deals featured on Groupon North America, including shooting ranges, conceal-and-carry and clay shooting, have been placed on hiatus while we review internal standards that shape the deal inventory we feature,” said Groupon spokeswoman Julie Mossler in an emailed statement to AOL Daily Finance. “The category is under review following recent consumer and merchant feedback.”

A Texas gun-shop proprietor, Michael Cargill, complained to AOL Daily Finance that Groupon canceled his deal for a concealed-handgun training course. Cargill said the Chicago company initially expanded the purchase limit from 600 to 1,500 buyers, but then a representative called him back.

“He said the CEO of the company decided that he’s not going to do any more gun-related deals,” said Cargill, who told AOL, “I’m asking everyone in the Second Amendment community to boycott Groupon, because the message they’re sending is, ‘Look, we do not want to support law-abiding citizens taking time out of their schedule to learn the safety surrounding firearms.’“
