John SI have read all the arguments for and against, but why do sellers put reserves on eBay auctions?  Why not start the item at a price that even if a single bid is placed will bring a sufficient return?  Does it cost less for the seller to set a reserve instead of a high opening bid? I placed a few bids today on reserve auctions.  I won two, but even with my maximum bids being 200% of book they did not meet the reserve.  If I had known the prices I may have placed a ridiculous bid to get the cards (both have been on the want list for some time).
