Thanks for all the responses. I was planning to buy bags of the various food stuffs and then put them into the 18 gallon Rubbermade Toughneck containers, purge the O2, seal them and forget about them (not really but put them away). The bags I've seen at Sam's and CostCo are any where from 5lbs to 50lbs. I was thinking that I would get more of the smaller bags; say 2 of the 25lb verses the 1 50lb. That way when I do rotate them (in 4 years or so) they will be more convenient to use.
Thanks for the advice Susan. I did ask a guy at work who I heard was Mormon; he was a lot more interested in converting me than helping me stock up.
