SoBe has an instant win game out…called Heads or Tails? CLICK HERE to play. I have won a Buy One Get One Free Coupon. I have heard that others have won freebies and even flip-flops. So head over there and play. I believe you can play once per day (without a code) during the promotion. Also, if you have a code from under the cap of a specially marked SoBe bottle, you can use that to play.
I have played it 4 times now…and won 1 B1G1 Free Coupon and 2 totally free SoBe coupons.
