This deal has ended.
Overstock, as always, has a wide selection (nearly 1200 items) of art prints and posters at very good prices, despite being overshadowed by AllPosters and Art.com. There are several new coupons you can use as well, including 7% off, 8% off for new customers and $25 off $200 (the first two expire 11/30, this last one 11/15). Many of the items are framed even at low price points (ie: these vintage prints from as low as $30), making the framing dirt cheap. Here are several other good pages. As always, shipping is only $2.95 and there is no sales tax (except UT, IN).
