About 3 months ago I purchased a new sprocket from a local shop. I knew when I bought it I would need a new driver that they didnt have in stock, so I ordered it at the saem time.
Fast forward to today, I just got a call that my driver has arrived after being on backorder for three months. The problem is that i've already gotten a driver off the internet and dont need that one anymore. I dont want to piss off the guys at the shop, because it's the only shop in the area that carries BMX stuff, and i've already spent over $2000 there building up my bike.
what do I tell them?
