Instant purchase is welcome! I'm looking to declutter, so I'd be happy if you buy in bulk! These are not rental returns!! 10% OFF for purchases of 30 or more books!! 20% OFF for purchases of 50 or more books!! If you pick out a few titles you're interested in and request a combined purchase, I will combine the shipping costs, which would normally be applied to each individual item. Please request a combined purchase. Check my profile for a large number of items listed. I plan to add more and more, so please take a look! Buying in bulk through a combined purchase request is a great deal! I will ship everything together in a cardboard box! I've set the prices lower than other listings! Furthermore, if you purchase multiple items together, the shipping cost will be for one item, making it an even better deal! Cheaper than buying at Book ○ff!? Purchases are generally first-come, first-served! I will offer discounts for those who purchase a large number of books!
