Right now you can print a coupon for Buy A Pepsi NEXT 20oz. Get Pepsi NEXT 20oz. free.
The coupon says “redeemable at 7-11” (which you certainly can try) but it is a manufacturer’s coupon so you should be able to use it at any store.
I actually like Pepsi Next- even as a diet drinker it wasn’t too sweet to me!
