Sign up for Chili's email club and you'll get a coupon for free chips and queso. You'll also get emails several times a month with coupons and special offers. Remember, you can opt out of the emails at any time after you sign up.
Signing up for email clubs is one of the ways that we save when we eat out. I've learned that you pretty much never have to pay full price for restaurant meals if you simply watch for coupons, sign up for email clubs, etc.
