Did you by any chance read the thread about logansryche's miserable failure at running a trading card store, which involved the only sale he ever made going south because he didn't actually have the merchandise, and he didn't have enough cash on hand to process a refund (which would have been about $10)?
That's not technically true... guy down in texas did actually buy a bulbasaur off me because he wanted to introduce his cousin into pokemon. He bought off me for a dollar and that included shipping. What got me in so much trouble was those damn gift cards. Live and learn,right? Not bring up past and smudge it in my face infront of everyone.
