Every first-time author is confronted by the reality of “Reserves Against Returns” as part of publishing economics. It is usually a shock and elicits a phone call to their agent crying “What happened to my money?”
Did you realize that book publishing is the only “hard goods” industry where the product sold by the supplier to a vendor can be returned? This does not happen with electronics, clothing, shoes, handbags, cars, tires…you name it. If it is a durable good the vendor who buys it, owns it (which is why there are Outlet Malls – to sell the remaining inventory). Except for books. Somewhere along the line the publishers agreed to allow stores to return unsold inventory for credit. In one sense, publishers are selling their books on consignment. Bargain books are actually resold by the publisher (after getting returns or to reduce overprinted inventory) to a new specialty bargain bookseller or division of a chain (which buys the bargain books non-returnable).
