For getting things on the cheapie side, I've found that they have a great sales rack.
Apart from that though a lot of things are marked as per retail outlet prices. They sometimes have some good deals on t-shirts as well.
But the main reason I come back here whenever I'm in Vegas is because I always need more Jack Skellington PJ's - and they deliver on this front.
I scored a great zip up hoodie as well for $10 from the sale rack. So you can sometimes find a great deal!
