Before each time you go to Chili's, re-sign up (with a new e-mail address each time) to get your 2 free coupons.
Combine this with the 2 for $20 deal and have a great night out!
The Free Brownie Sundae comes after you sign up and print out the coupon for chips/queso. You have to put in "last 4 of credit card and your last name"..
but you can just put any random 4 numbers and will be fine
BONUS: Your Karma will go up by +1! Just for signing up, Chili's will donate $1.00 to St. Judes to help fight cancer in children! (up to $1,000,000)
