Hi! For December 2013 only, we're offering a Holiday Special of 25% off the prices of all our existing paperbacks and hardcovers. This discount will appear in your shopping cart. (Offer not available for pre-orders, which get free shipping, instead.) We take credit cards, checks/cheques, and PayPal, and you still get free shipping on all orders over US$40. Thanks for supporting Just World Books! ~ Helena Cobban, founder.
