Who doesn't like free shipping?
Add at least one of the "featured" books and enjoy free shipping on the whole order.
No minimum spend is required apart from purchasing a "featured" book. This list can change quite frequently so if there isn't something there right now for you, there might be next week or next month. Be sure to check back regularly!
But…..shipping is cheaper than the books?
Also….bookdepository - free shipping and get only the books you want without having to buy random books.
