Walgreens (1.5% cashback) has a coupon code out for $10 off $40+ purchases ending today: TEN40 (only exclusions are pharmacy and photo orders).
Some ideas on how to use it:
Pillow Pets are $19.99 each, so with coupon two would be $30 shipped (plus tax)
Blue Diamond almonds are two for $4, so you could get 20 cans for $30 shipped (plus tax)
See what other goodies you can find to save ten bucks on!
