careful! i had this happen finally sent her an email saying pay OR respond and let me know that she did intend to pay within 2 days or i'll relist item and file a non paying bidder alert (you can't do negative feed back as a seller anymore... totally wrong but thats the new ebay). She finally paid (she got 120$ worth of product for 25$ i lost at least 100$ when shipping was counted but hay that's ebay). So I thought nothing of it sent the package next day. Next time i log into ebay (don't use it much) my feedback is down to 92% the woman gave me a negative and said I DEMANDED she pay or else... i did nothing of the sort and i tried to have the feedback revised, she refused, then sent me a nasty email, so i outlined why she was full of it in reply... crazy lady apologizes and offers to remove the negative feed back... but she already denied the request for feedback revision and you can only request it once so I'm SOL and have a terrible ebay rating for the next year not even worth selling anything....
so in the future i will just file a non paying bidder after the time is up and skip the pleasantries because i shot myself in the foot....
