That's right, we're not kidding: this week, you can get a burger from Wendy's for just a quarter. It's just for a Wendy's Dave Single, and if you spend $20 before tax through Grubhub, you can grab one of those for just 25 cents.

Wendy’s teamed with Grubhub on the 25 cent deal which works as long as customers have a subtotal of at least $20 before tax, tips and fees.
