$1/1 Post Great Grains Cereal Coupon + Walgreens Scenario

$1.00 off when you buy ONE box of POST GREAT GRAINS Cereal

This week when you buy 4 boxes of Post cereals at Walgreens for $10, you'll get a $3 Register Reward back!  With four $1/1 box of POST GREAT GRAINS Cereal coupons (you'll need 2 computers to print), you'll pay $6 and get a $3 RR back, for a net cost of $3 for 4 boxes!  If you only have one computer, there is also a $1/1 manufacturer coupon on Target's site and $1/2 Post cereals found in the 11/6 SS!
