how many MRE's in a case
1 The average case has 12-24 MREs. 2  After some general research, it has been found that anything around 24 pounds for less than $25 is a fair deal. 3  According to SurvivalAcres.com, a case that contains 12 meals should cost around $50 while individual meals should average around $4 to $7 per meal when bought in bulk. Aside from the military MREs, there are now civilian MREs. 2  They can commonly be found through someone in the military, surplus stores, gun shows and auction sites such as eBay. 3  The average lifespan of a MRE is about 7 years. 4  However, if it is exposed to high heat or extreme climates, this number can reduce a lot.
