MRE and you have to give up taste
LDS is very highly recommended by everyone I've talked to.
http://www.providentliving.org/channel/0,11677,1706-1,00.html
Most of their locations are open to the public so you don't have to be a member of their church.
Not sure where you are in MI, but they have a location in Farmington Hills.
Order forms and such are on the left side of the aforementioned site page.
In most locations, you make your selections and can/bag the stuff yourself (with their guidance as needed).
Sam's club - if you already have the buckets and gamma seal lids, you can't beat their price for bulk rice, beans, sugar, spices, & flour.
otherwise, providentliving and beprepared.com aren't bad.
cool.
where?
