Hurry on over and load this digital offer to your account for a completely FREE 12-pack of Mountain Dew Cans! I found the offer in my account this morning – pretty exciting! It’s looking to me like everyone will have this offer, but it has a loadable limit. Once it reaches the loadable limit the offer will disappear. It’s also important to note that the offer’s redeem by date is in 2 days (12/31).
