Since you're discussing bulk packaging in another thread -- for what it's worth, I'm interested in the opposite. Single meal packs - not unlike the single-meal sample pack that got me hooked on Queal.
After the multi-flavor test pack, I ordered 26 packs of the flavors that I liked - I was thinking that I'd be "munching" through them in no time, but that hasn't been the case - they're just not portable enough for me.
I'm not sure about anyone else, but the problem for me is carting those 3-meal packs around with me (they're about 500g each). In addition, I can't tell you how many times I've found myself wondering how come that last meal left in the pouch has MUCH more than 5 scoops worth left over -- which means that I must have short-changed myself on one or both of my other two shakes. Then there's the problem of scooping the powder without making a mess -- Single meal packs would ensure that I don't get the mixture wrong and also prevent me from making a mess with the scoop.
Plus there would be no need for that (costly?) re-closing velcro strip.
Might be interesting to poll how many of your current customer base actually go through 3 Queal meals per day -- I'm guessing that was the premise for deciding on a 3 meal pack.
