Wendy's is offering any size of fries for just $1. That's right — whether you want a small, medium, or large option, you'll have to pay just $1 for your fries at any participating Wendy’s location. The "FryDay" deal will last for a limited time, but there hasn't been any word on how short or long that limited time will be, so it'll be better to head to Wendy's sooner rather than later to get the discount. Of course, Wendy's is no stranger to over-the-top food deals.
