Chaosium has a great policy of selling their shopworn books (fiction collections and rpg books) at 50% off- I picked up a handful a few months back and then promptly forgot to mention it on here. I don't mind shelfworn books myself- gods know my collection is mostly made up of used books, and anything I own is bound to get battered sooner or later considering all the time it will spend in a backpack, backseat of a car, the woods, the bathtub, etc. Chaosium has always put out extremely good products, and I could hardly tell these books were seconds- maybe a dogeared page here and there, but certainly nothing that could interfere with reading.
