Do you guys wait after someone says they'll take it do you give them to pay before you put the item back up for sale? I had a guy say he'd take a knife of mine and to send him my paypal address. Well, I did and 3 days later I've still not got payment. And, he's still logging in to the site and actually has even been saying he'll take other knives in other threads since mine. I've tried e-mailing the guy, but I get no response.
