A 'reserve' price can be used in an auction so the seller can say, "This is the lowest price I will sell this item," and still start the auction at a lower price that will attract bidders. No one knows what the reserve price is until you bid at or above it, and no one wins the autions unless that price is met. It can be annoying because people bid, but never win, or the actual price is so high that most people can't really win. 'No reserve' means that you won't have to worry about any of this; that the listed bid price is the actual price, and you have a chance of actually getting the item at or near that price. - Terry
