Ok, you know you've done it. While working on your bike you come across a bolt or screw and you dont have the right socket or tool for. You drive yourself to Wal-Mart, buy the tool. You use it, put it back in the package and take it back to Wallyworld for a full refund. Since I had my bike (6 months) Ive done this a few times(ghetto fabulous). I was just wandering, what are some things you bought with the intention of using it and taking it back? Be honest.
