Wendy's Coupons for Michigan Residents
I don't know if there are sites for other states, but this one is for Michigan Only. As far as I know this is an official Wendy's site.
The current set of coupons expires June 30th, 2008, at which time they will issue new coupons. I've been using this site for a few months now, and you can print as many coupons as you wish. Also, on the back of the receipts you can take a Web survey and get a code for a FREE float (YMMV on the Web survey...our local one will also let you get a Frosty instead).
There are currently 4 coupons that print when you click any one of them:
1. Buy a Single get a Single Free
2. 2 Chicken Sandwiches for $5 (original, grilled or spicy)
3. 2 Double Cheese for $5
4. $1 OFF any Large Garden Sensations Salad or Wendy's Combo Meal
