If you frequent Taco Bell often, or more than you should, here's an opportunity to stretch your dollar a little further. Forum poster keljai has found a Facebook coupon where you can get a free Fries Supreme with purchase of any 20oz drink. While we'd recommend eating anything, even something as delicious as Taco Bell, in moderation, this is definitely a good deal to take advantage of; especially if you buy fountain drinks anyway.
To get started, you'll need to like the Facebook page here, print the coupon and present it when checking out at your local Taco Bell. You must have the coupon handy or you'll be out of luck, unfortunately.
The deal is live now but expires on February 3.
