Its unfortunate that just because this Dollar tree is in South phoenix they don't keep it looking clean. It seems they are short staff because they always have a mess everywhere. Just because it is a dollar store doesn't mean the cleanliness and appearance needs to be horrible. I have gone to a few Dollar trees and this one is by far unorganized, unclean and you can totally see under staffed.
For management: hire people who want to come to work and add a few more people in order to make it a nice store. Its not the greatest area but don't make it feel worst by not caring for it.
