I am again offering my 9 books for 3 credits, 12 for 4, 15 for 5, etc on everything on my shelf. No orders under 9 books, please. Anything over 9 is added at 3 for 1, with no maximum. An alternate choice or two would help, in case I can't get your choices deleted before someone else orders. Offer expires Sunday at midnight and all orders go out Monday.
