Simply go to this page and then click on the 20 oz. or 2 liter coupon that you’d like to receive.

On the next page, you’ll need to fill out your email address and date of birth. On the next page after that, fill out your mailing information, as this coupon is physically mailed to you instead of being printed off.

I just requested mine and it said that I will receive the coupon in 4-6 weeks. I don’t know how long this promotion lasts, so jump on it.
