I reuse a lot of the plastic bags. But I imagine I'd run out of use for ice packs after a while. Given the amount of cardboard I have to take to recycling from Amazon and elsewhere, I'm not sure a bit more makes much of a difference.
But the menus mostly don't excite me that much. And if I'm going to spend that much effort I have tons of cookbooks and online recipes. Your experience sounds like the one week I tried it. There was a pretty good recipe. An OK recipe. And then some obnoxiously complex hamburger recipe that wasn't even all that great.
