Menards

Menards makes it somewhat easy to find made in USA products in their home improvement stores.
Every few weeks they run a made in USA flyer that lists pages of products made here.
They also have some labeling on the shelves for items made in USA.

I know they carry several rugs and door mats manufactured here, but I was delighted to find this fun number with an owl on it during my last visit.
When in the store, you can also find American-made toys, housewares and more. I recently even saw an apartment-sized stove in the store with a made in USA label on it.
