Question about multi packs

Due to some dietary restrictions, my wife has a limited amount of choices in canned beverages. We love to have those for days at the pool or the beach.

However, almost all of the beverage choices are sold in multi packs with four or more flavors in them. In most of these packages, there’s one good flavor, one OK flavor, one that’s kind of gross and one that taste like butt crack sweat.

Why do beverage companies insist on doing this? If you sold the packages with one flavor per package, you would know what works and what doesn’t, but as it is, the fact that your canned butt crack sweat sells as much as your best flavor hides the painful truth.

I’d love an answer for this before I start cracking open the boxes and repackaging all the good flavors in one container before taping it shut
