Have done it (listed at a fixed price)  it requires re-listing for several weeks and eBay are at the end, the beneficiaries, perhaps are they (buyers) used to see my fixed priced items eventually getting re-listed in the auction format and they now wait for that change to take place before risking a bid... It is a fact snippers are all over my auctions, some are quite nice and I am happy to have them, they are sooo honest that they offer me more sometimes so guilty they would feel, I think I will let the rest of the stock go and will call it quit...
