Buy More, Save More offer valid now through 11:59 P.M. ET 12/27/11 online, by phone and in stores. Offer valid on sale items only. Excludes full-priced merchandise. Discount will be applied at checkout. No promo code needed. Free shipping on orders over $100 is auto applied in the cart as well.
Also, quick tip - if you were one of the people who tried to order over the Thanksgiving holiday, and got the 40% off coupon, it stacked for me. So I bought my things, for 60% off, then 40% off that. IDK if it will "stick", but I got my order confirmation as that lower price.
