IMO the problem here is the size. I'm not going to spend $15 on a flavoring system I have never tasted, when I could get an additional 100g cissus or almost 2 months worth of sesathin. Additionally I 'd rather be able to add 2 different flavors to 3lbs of protein each, rather than flavor 6lbs of protein at once
maybe if you sold them in 1oz for like $7.50? Then we could also try a bunch of flavors...
Just figured I'd toss some ideas out
