Now that most book auctions are no longer viable on another well-known site and in fact only 4% of the books listed there are auctions, I have opened a store just for book auctions. All auctions start at 99p with no reserve and p&p at cost, so there is the oppoortunity of a real bargain. The store is still under construction, but the first few books have been listed and more will added steadily. You are invited to come in and have a look round but beware of any builders rubble lying around!:
