Yummy! If you are heading to go eat at On The Border anytime soon, you’ll definitely want to take advantage of this deal. Currently you can snag some free queso or sopapillas by signing up for their club cantina (email subscription). After you fill out your information they will send you a welcome email with this printable coupon included! From my email it looks like the coupon expires 2 weeks after you receive it so keep that in mind.
