I skimmed the other reviews posted so far and I'm actually surprised no one has mentioned the NOISE.
I'm between this Walmart, Christown, and the one on 35th ave and Bethany. Sure, the Metro Walmart is large and carries more products, but there's a bone jarring humming coming from the ceiling through most of the grocery section. It's this loud, deep, and vibrating hum like a thousand a/c units are about to explode on the roof or something. I've never heard a noise like this anywhere except scenes in moves when UFOs are landing. It's bad enough to where I don't like having to go to this Walmart even though I should just because of the wider selection.
