Walgreens again offers a 4" x 6" Photo Print for 33 cents. Add five to your cart for $1.65 and apply coupon code "5FREEPIX" to make it free. Choose in-store pickup to avoid the 99-cent shipping fee. That's tied with yesterday's expired mention, a savings of $2, and a great deal for same-day pickup photos.
There are lots of things Uncle Sam can't touch — so long as you play by the rules.
