I forgot about the month long deal at Walgreen's when I posted the Listerine coupon yesterday. Here is an even better deal:
Buy Listerine Whitening - $5.49
Buy 1, Get $2 RR, Buy 2, Get $4 RR
use the $1/1 printable (use zip 60606)
plus the $3/1 in ad coupon
Free plus $0.51 after coupons and register reward!
