Help, I am new to selling on Ebay! I have some things on there at the mo, collectors items. One buyer kept bidding and then his bid would disappear (I didn't even know you could do this?) Then I had a message from him saying would I accept a postal order. DH pointed out I only had 9 transactions on my account so perhaps he didn't trust me, so I sent a nice reply saying yes no problem. Then he put in a large bid and sent a message saying would it be ok if he paid in about 5 weeks as he wouldn't have any money until nearer Xmas, so I said sorry but no, please don't bid if you don't have the money etc etc. His large bid disappeared. Now he has started bidding again and sent yet another message saying he has been to the bank and gots lots of money but can't get to the Post office so is it ok to send the postal order in about 10 days time?! He keeps putting in small bids which disappear about half an hour later. He has an otherwise good rating but is starting to annoy me. Would I be unreasonable to say no, I want the money staraight away, or is what he is doing common practice on Ebay? Auction finishes tomorrow evening, was a 10 day one.
