When you did a search, you used to get only lots that were available for bid, auction style. Recently, eBay started including all the BuyItNow and eBay Store stuff that fits you scan in the results. You can exclude these by clicking the Auction Only box at the top of the results.

When I scan for chips, I initially get over 7000 lots; when I say Auction Only, I get maybe 300-400.
