I hate that the email about the promo is so vague. nowhere does it say
which participating products will have double points. I input the Propel, but don't bother because those did not double. I had 2 other 12 packs but don't remember which exact product & did not double. I, too, had at least 1 diet Barq's 12 pack come back & say that it was already redeemed. I had to empty out the cans to get the code so I know it was new. I had several cap tops that also came back "already redeemed". It's very annoying & the worst part is that it seems to take forever. Could be my computer, but it was very, very slow. It just seems a big joke & I think they are just trying to make you mad & just give up. Seems like a waste of time!
