Let me be straight with you. When faced with the choice of Target or Walmart, I will almost 100% always go to Target. I've seen too many stories/documentaries about the ahem...Walmart way, and just prefer the way Target does their business.
BUT. If you must go, remember this is one of the better locations.
I was in the Arboretum and needed to pick up some nail polish remover, and moseyed on in. This Walmart isn't the biggest...it's not a Supercenter with nail salon, tax prep, alterations shop or anything like that, but you'll find a good selection of goods. (There IS a Subway sandwich shop.)
Compare this to the Walmart on South Tryon, and it's night and day. This one is spotless and the employees don't seem like they're bored out of their minds. The shopping experience is just better. More cashiers, better organized rows.
Still, it's Walmart. What else can I say?
