Does Wal-mart carry a .410 single shot? I haven't been there in a while and I don't remember seeing one. I am thinking about getting one for my 7 year old sister. How much would a used one cost? I am 11 and I am going to mow yards, do house repairs, and make websites for money. I am also trying to buy a Mossberg 835 for $260 at Wally-World. Any replies would be greatly appreciated.
