Sorry but I don’t agree with you, I’m also into frugality and so on, but you are being controlled by the money and for what?? 
Ok let’s say in the most optimisim future you will get it to every supermarket in the us, and you will have $10mil or even more. what it will give you? you spent all your life live like shit(no travel, not going out) with unhealty food (coke and potateos) to make this $20mil or whatsoever in age 50–60. is that really worth it? what you will do with it that old, i think you spent way too much time. the basic idea is great but take it like you did has no meaning for me esspically when it’s all about the damn money
