I have had this happen many times lately where an ebayer pays before I have sent an invoice. the destination is never known till the auction is over. I specifically request that they wait in the listing but it is obviously ignored. SOMETIMES THEY PAY...
I bid on a lot of postcards and lost pictures overlapped a bit so hard to recognize specific locales ,asked seller if he could send me pictures of requested postcards{4} and EBAY BLOCKS IT.auction over what is the problem????
what is the purpose on preventing ebayers from seeing what you buy and sell in the "view items" section of the feedback forum?
does anybody out there have the same question like when you are constantly outbid it is good to know what that person's interests are?
when checking ebay members feedback to see what they buy and sell some members have blocked the "show item" below the date of the feedback,not every ebayer only some of them ,what gives?
