Gravy and biscuit mixes at WonderBread store are really good. I passed on the news about the coupon last week at the Wonder Bread store, this week it's $2.00 off a $8.00 or more purchase. The coupons are available at the store, just ask at the counter, I believe the lady at the counter said the coupons are also in Harry's Wooden Nickel.
I have found these gravy mixes to be really good, I use the country gravy mix when making biscuits and gravy and the country chicken one when doing chicken fried steak. The cheddar and herb biscuit mix was also very good.
They also have sugar free cookies at the Wonder store, so using this coupon is a great way to save a little on those, since they are so expensive. I don't believe there is a limit, so you could go in more than once this week to take advantage.
