From the 7UP website:
We’ve reinvented Diet 7UP with more natural lemon lime flavor. It is even more refreshing, and guess what! There’s even less diet aftertaste!
We’re letting you make the call on the New Diet 7UP. While supplies last, we’re giving away Diet 7UP Taste Challenge kits. Each kit contains the New Diet 7UP and two other competing diet lemon lime soft drinks. Try each of the soft drinks, and let your taste buds tell you which is best. We’re confident you’ll love the New Diet 7UP.
