Become a fan of Planter's Nuts on Facebook to get a coupon for $1.50/1 5.75-21.25oz Planter's product. You should be able to print twice.
Apparently, the trail mix sells for $1.99 at Walgreens, and there is a $1/2 coupon on the March Walgreen's coupon book (available in store). Pair this with the 2 of the $1.50/1 coupons mentioned above to receive two bags for free! I'm going to try to stop at Walgreens tomorrow...I'll let you know if this deal works out for me!
Thanks to Mashup Mom for the heads up!
