Citi Merchant Services and First Data Corp. are refusing to process any credit card transactions between federally licensed firearms retailers, distributors and manufacturers -- a move which will severely limit available inventory of firearms and ammunition to military, law enforcement and law-abiding Americans.

The first company to be affected by this decision appears to be firearms distributor CDNN Sports Inc.

"We were contacted recently by First Data/Citi Merchant Services by a June Rivera-Mantilla stating that we were terminated and funds were being seized for selling firearms in a non-face-to-face transaction," said Charlie Crawford, president of CDNN Sports Inc. "Although perfectly legal, we were also informed that no transactions would be processed in the future, even for non-firearms. I find this very frightening."

To voice your concern to Citi Merchant Services and First Data Corp., please contact June Rivera-Mantilla at 631-683-7734 or her supervisor Robert Tenenbaum at 631-683-6570.

According to the Merchant Talk blog, Citigroup/First Data (Bank of America is rumored to follow!) will be terminating the processing agreements for all firearms dealers that sell in a non-face-to-face transaction.
