Yellow Red Bull is definitely the best flavor they make. It’s so good. I drink it instead of coffee, because coffee hurts my stomach. I love this stuff. I order a case about every other week and drink one on my way to work. On a bad day, I’ll drink a second one while I’m at work. I like that I can just order the case instead of buying a bunch of little cans at the grocery store, and buying the case is cheaper than getting the four packs. I miss when this flavor was available in a fridge pack.
