Groupon has canceled, at least temporarily, all of its scheduled and ongoing gun-related promotions, Matt Brownell at Aol Daily Finance reported.

"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," a Groupon spokesperson told Daily Finance.

"The category is under review following recent consumer and merchant feedback."

Michael Cargill, the owner of a gun shop in Texas, said that his Groupon deal — for a concealed handgun training course — was canceled and that the representative told him Groupon CEO Andrew Mason was behind the decision.

"The Groupon representative calls me up and he says that 'Well, because of the CEO, he's decided to suspend all Groupon deals related to handguns, concealed handguns or anything dealing with guns period," Cargill told FOX 7.

Cargill is now calling for a boycott of Groupon.
