Education Gift Science Book Eureka! Great and similar items

Buyer pays all shipping costs. I accept returns within 14 days of receipt that are in original condition—which means that new items are still new and used items look as good as they did when they left me. I take great pains to package items immediately after listing them so they will look exactly like their listing pictures when you open up your shipping box. If the item was in its original packaging when listed, it must return to me that way. If it was attached to a card by a small plastic tab, it still should be. It should look exactly as it did in my listing pictures or I cannot relist it using that original listing. I cannot accept a returned item that smells of cigarette smoke.
