Dr Pepper has a promotion running around this opening weekend of college football. I'm not sure if you get the coupon for the free coupon only under their promotion details, but the confirmation for registering on the site currently says you will receive the coupon in 5-7 business days, so it's worth a shot regardless. May be very limited time only.
UPDATE: This has indeed ended quickly, hope you got your request in fast!
