FWIW I purchased an 870 Express online (shipped to my local FFL) from the link below. The discussion over the phone, the follow-up info sent to me electronically, and the delivered product were exactly as represneted. They're in Houston. Just for what it might be worth. I got good service from them. Have never used Gunbrokers or GunsAmerica. YMMV.
