Just started selling today on Alibris. Well, just opened an account I'll say. Not sure if there will be much selling the way this is going so far. Attempted to list a DVD by UPC. No match found. Go to alibris.com and enter UPC, there it is already for sale. UPC? 081758220841. Is this normal? I was hoping to escape these sorts of issues that I have on Amazon. Hope I haven't made a mistake by opening an account here.
