Groupon Inc., the largest provider of online daily deals in the U.S., halted gun-related offers amid nationwide debate about weapons sales following a school massacre in Newtown, Conn.

“The category is under review following recent consumer and merchant feedback,” Julie Mossler, a spokeswoman for Chicago-based Groupon, said by e-mail, without elaboration. The suspension covers areas including ranges and clay shooting, she said.

Dick’s Sporting Goods Inc. last month halted sales of military-style rifles similar to the one used in the Dec. 14 Sandy Hook Elementary School carnage, which resulted in the deaths of 26 pupils and staff members. Wal-Mart Stores Inc., the largest seller of guns in the U.S., continues to offer the weapons at about 1,200 of its almost 4,000 stores.

The Groupon suspension was reported Sunday by the Los Angeles Times.
