I'm borrowing this from CVS Snacks
If you add both the 8x10 AND the 5x7 to your cart and use the promo code ENLARGE your total will be over $5 and you can avoid the $1.49 service charge. CVS photo online uses glossy paper, which I don't really like, but HELLO? it's free. (Plus, grandparents usually don't care if they get glossy pics!)
don't forget: the code expires tomorrow, sorry for telling you at the last minute!
