I guess if you are going to use secondary ID's, instead of your main one, that sort of problem goes with the territory. I'm the kind of seller that would cancel your bid, just because you have only 6 feedback. Some sellers don't want to help Newbies learn the ropes on Ebay. I myself might have interpreted your lack of feedback as a lack of experience. How would I know you have other ID's with thousands of transactions? My policy is to automatically investigate any bid from a buyer with less than 5 feedback or less than 3 months experience or both. I do agree though, that Ebay should tell you which seller doesn't want your bid. I think you could find out by looking up your ID in Advanced search, and then click on the items that ID bid on. Ebay would put a note in the BIDS section, recording the cancellation, and reason for it. You could probably figure it out for yourself, if it was important to you. And I apologize in advance, if you ever get bounced from one of my auctions, using your secondary ID, you will know it's me though, cause I always sign my cancellations - ADMINISTRATIVE CANCELLATION. 🙂
