Borders began a new website recently, independent of amazon. They currently have a whopping 40%-Off coupon (BC4777) that you can use towards 2 items. I pre-ordered the Godfather Coppola Collection for $61.79 (they list original price at $102.99 even though amazon lists it as $124.99).
They also have Baby Mama for $24, Leatherheads for $24, Sweeney Todd for $24.59, Jerry Maguire and Rudy for $17.39 each, the Omen Collection for $75.59 (all after the discount, of course)...and as long as the order is over $25 there's free shipping! And their shipping is pretty quick once the package is sent.
For those like me still sitting on Borders gift cards, this is the best coupon code I've seen. They even have the Heroes sets available, Season 1 for $61.79 and Season 2 for $38.39!
