You can get free Baconator fries this week

The fast food bacon battle is sizzling: Wendy's is offering a free treat all week. 

The fast food chain is giving away free Baconator fries through Sunday through its app.

You can get a free order with any purchase, in-store only. The offer will reset daily, but can only be redeemed once per day, per mobile app account. 

Wendy's is hoping its bacon fries will rise above the rest, as restaurant chains have been dishing up bacon specials and adding new menu items in recent weeks.
