There are two other walmarts in this area and I suggest you go to them if you have to return anything unless you enjoy having your blood pressure go up and felt like a criminal.
According to one of their employees, they are the "best" store in the country and have all the commercials filmed there which I highly doubt.
Whenever you try to return something they give you a dirty look and will argue with you on why they won't take your return. I had one person run their finger around the shrink wrap of mascara to make sure I didn't try to open it. The mascara was only $2.
I gotta say this is a huge Walmart but like all Walmarts expect to wait in line for about 1,000 years till you get to the register.
It's usually calm at night time but the night crew that work there are really weird.
