Sometimes B&N offers a coupon via my email, like this one:
This discount will apply after my member card's discount, but it's still money off my purchase. Because I'll be in Roanoke on Saturday, I plan to stop at the Tanglewood B&N.
But there's more: I figured I'd spend at least $25 on books, so I bought a $25 B&N gift card at Kroger last Tuesday. Buying a gift card at Kroger gave me double points toward my discount Kroger gas purchase, so I'll save on a non-book purchase, too.
