EDIT: This offer is no longer available.
Sign up for Pillsbury's newsletter and receive around $5 in exclusive printable coupons every time they send out an issue (which I believe is once a week?) I'm a horrendous cook (ladies, pretend you didn't hear that!) and so their biscuits are a lifesaver for me in that even I can't ruin them. I'm pretty sure had I not discovered them in college, I wouldn't have made it past the age of 20.
Some of the current coupons include $1/any two Pillsbury Cookie Dough, $0.50/any two Pillsbury Grand Biscuits, and $1/and two Yoplait Kids Yogurt.
