Neither!
I won't shop at Walmart because the staff is rude. They actually go out of their way to be nasty.
I won't shop at Target because they did some nasty, sneaky, and underhanded things to get permission to build a store in my town, and lied to the homeowners nearby. Yeah, that's how you get ahead in corporate America, but they were egregious. Nobody in my town will set foot there.
Thankfully we have alternatives...
