A lot of the physical open to the public stores took a beating before South Dakota v Wayfair was decided in June 2018, since it was trivial to spend ~7% less by shopping from a website with a presence outside of your state.

I doubt Microcenter ever expands to the number of locations that BestBuy /circuit city/compusa/etc had, but it might have enough of a market for one or two locations in the top 10 to 20 metros.
