At one time there was a DMV next to Target in the Springfield Mall, but the DMV was never inside the store itself. There are no Walmarts in the DMV, nor are there any DMVs in the Walmarts.
Most mangers are Chinese. The title of your post asks about Indian mangers, but the body is asking about Indianian mangers. There may be mangers made in Indiana, but they don't sell them in Walmarts outside of Indiana as far as I could determnine. I searched for manger manufacturers in India and could not find any.

American Indians perhaps make mangers but they do not seem to have a significant distribution network outside of the reservations. Are you referring to a Walmart on an Indian reservation which sells locally-produced mangers?
