I deal almost exclusively on eBay. Most of that is automatic these days. Win the auction and pay almost immediately. Item is shipped or marked for shipment within an hour. Then there's the occasional guy that takes two to three weeks to ship the item. They can do this, it's within the rules, it's just aggravating when you're used to everyone else doing it much faster. I average about 7 purchases a month and in a years time I might have two that take forever to ship.

In over 1000 purchases, I've had two that sent me someone else's item. Both were passed on to the correct individual, I got the correct item returned once and refunded for the second. I only had one guy that screwed me over, said he lost the item and couldn't find it. I was refunded.
