I know they don't have any stores in SD, but here in Michigan (and southern IL) we have Gordon's Food Service and they sell the 6-in-1's in the 10# cans. You might try to look for a local store that is like that. One that sells larger quantity goods that would sell to restaurants or caterers. I was surprised for find that my local GFS has 6-in-1's, high gluten flour, heavy pizza pans, good cutters, big bags of pepperoni, lots of good stuff.
