I had three purses for sale on eBay. A used Coach sold as well as a pricey LAMB bag. Problem is, the person who bid and won the LAMB bag is brand new with no feedback. It's been four days and I've heard nothing from them. I've sent emails, invoices, etc. I require payment within 3 days. I've read other posts here saying I have to wait seven days to post a non-pay against them but can I relist the item immediately and then block someone like that from bidding again? Or, in the future, can I block or remove bids from people who have no feedback or very little feedback? I had over 30 watchers on that bag and the one person who actually bid on it is a non-payer. What a waste of time and money! Thanks for any info.
