So, remember a while back when we were doing our Bug Out Bags?
I was all set except to pack the food. I finally remembered to order our MREs.
I got a one week supply [21 meals] of MREs from Emergency Essentials. This pack did not include heaters, so I also got a dozen MRE heaters so we could have hot food if we need it. The food choices are widely varied and random, so you don't know what you're going to get, but you can't beat the price - on sale for $84.99.
A reader got this set from Readymeal.com and her set did include the heaters. 12 meals for $69.95.
The prices for MREs are all over the place, so shop around.
