I could never find the frostbite one. It’s okay though cause I try to only drink sugar free (the zeros have been the best soda addition—tastes so much better than the diet version and once you get used to it, you do not want to go back to regular). I don’t think I ever got the Mountain Dew free after offer rebate for the 2 liter but I did get the Pepsi zero one. A few months ago, you could barely find the zeros because they were only producing certain flavors. I’m glad to see the shelves starting to have them on a regular basis so I don’t feel the need to stockpile like it’s the last I’m ever going to get 😂
Also what I do if I can’t find it but according to the app, Walmart has it somewhere—I do a grocery pickup and try my luck. Sometimes someone finds it but it remains a mystery as to where it was.
