I've heard a lot of people say that they find the best deals on bulk staples (oats, flour, etc) at Amish/Mennonite stores and I was wondering if anyone knows of one? I'm in central Iowa so I know it's not likely that there is one around here, but I would be willing to drive to one once every few months if I could really stock up.
all i can think of is Stringtown (that's the name of the store) in Kalona. i've never bought bulk from them but i'm pretty sure that they do it. However because they are amish they don't have a phone so....you may just have to venture down there.
I was going to recommend Stringtown also. They are actually on the road to Kalona. Just down the road (not far) from the cheese factory. They do sell in bulk and have great prices, especially on spices! They don't have a huge store though.
It is fun to look around and see all of the non-electric items. Like the gas powered irons! Very expensive!
Lamoni has a large Amish community. Possibly they have a store as well? I know they sell baskets near the state line at the convenience stores. Maybe you could ask one of them if you see them when passing by?
