We provide FREE GROUND SHIPPING for any retail order of 50 books or more. Wholesale orders are not eligible for free shipping. We ship by UPS, Priority Mail, or Book Rate (Media Mail), depending on the customer’s choice. You can choose which option you prefer at checkout. Typically, Media Mail will be your cheapest option. Priority Mail is a good option for fast shipment on orders up to 20 books. UPS is usually the best option for orders over 20 books, if you need faster shipment.
