I dunno about cost effectiveness but we ordered our MH food from Karst Sports.
http://www.karstsports.comWe needed #10 cans of food to put into ziplock bags and at the time, as I recall, it was hard to find MH freeze dried due to the large number of forest fires in the Lower-48. All or most all of their production was going to the fires.
Anyway, Karst was good and fast for us. Ya might wanna try 'em.
Hope this helps some.
Later, B.I.F.
