Local gun store charged me $19.99 for new 31 round 9mm mag. By accident Im sure. When I realized it I turned back to him and asked him to get me another and to count how many he had in stock. He turns and asked the other guy workin there how much they are supposed to be. So they realize that instead of 49.99 they charged me 19.99. I asked if they wanted me to pay the difference and they refused. All in all, I didnt get to buy the whole lot at that price but I did get one!
