Thriftbooks offers quality used and new books, accurately graded, at everyday low prices, delivered directly to customers. They are the world's largest online independent used book seller, hand-grading every book in their inventory and offering books in a variety of formats and conditions for their customers. Their ReadingRewards loyalty program continually delights loyal customers with free books awarded for their points earned.

Thriftbooks offers educator discounts under their ReadingRewards program, and those are now extended to HSLDA members!

Get a free used book (valued at $7 or less) every time you buy four or more books. And for the first year, as a verified teacher, you’ll be bumped up to Literati status (their highest-earning ReadingRewards tier) so free books add up even faster.
