Safeway Coupons

Have any of you tried advertising through the coupons that print at the registers? In our case, the Safeways around here have a separate printer that prints 1,2,or 3 coupons when you checkout. I personally look at them and was curious what you guys think of that program.

It's roughly $200 to $400 per month for at least 1 year contract. Thoughts?
