Go here and Like Wendy's on Facebook. Once you do that, click on the Tour of America tab and scroll down until you see a small orange box that says FREE Dave's Hot 'N Juicy Single. Click on the orange box, and you'll be able to print a coupon for a FREE Hot 'N Juicy Single when you buy small fries and a small drink.
I just printed my coupon, and it expires one month from today. This coupon should get us a full meal for a dollar or two cheaper than a normal combo meal.
Thanks Common Sense with Money!
