The fine print at the bottom of the coupon I received the other day from Borders (verbatim--really):
Valid with Borders Rewards membership only. Certain exclusions apply. Coupon cannot be combined with any other offer, including but not limited to "3 for 2," "Buy 4, Get 5th Free" or "Buy 1, Get 1 Half Price" offers. Excludes previous purchases, non-stock special orders, gift cards, newspapers, magazines, comics, coupon books, eBooks, digital downloads, self-publishing programs, Smartbox, Rosetta Stone® software, shipping, and all electronics, including but not limited to the Sony® Reader and the ZuneTM. May not be combined with other coupons, sale pricing, or corporate, classroom, or other group discounts. Original coupon must be relinquished at time of purchase. Single-use coupon. One coupon per customer during the valid period. Void if copied, transferred, and where prohibited by law. Any other use constitutes fraud. Cash value .01¢. Not redeemable for cash. Valid only in U.S. stores and at Borders.com through 12/28/08 midnight EST.
I am tempted to add: Garnish with Fluffernutter. But that really wouldn't make any sense.
