Well, it's official: Barnes & Noble is ready to step up and take Borders' discarded tiara as the king of coupons! (Maybe a tiara isn't sufficiently kingly?) Last week's 50% off coupon worked flawlessly at the store for me, so this coupon for 50% off kids' picture books should be equally smooth. (The printable coupon link is in the comments section.)
There's no stated limit for the number of books you can buy, so I think everybody on my list is getting a copy of The Very Hungry Caterpillar for Xmas this year. Don't tell!
