NYandCo has awesome stuff right now. It's a little bit hard to find in store because they have this weird lay out with the jackets in different places, and the pants organized separately by cut instead of with the jackets they match with, and their website has absolutely nothing. But if you go and see in store and ask the sales people, they have great stuff that's actually really cheap.
I went to The Limited first and bought a pant suit for 230, and I was happy with the fit but kind of meh about the fabric. Went to NYandCo and found a suit that was awesome, both fit and fabric, for about 80 bucks. (I had to pay 60 to get the jacket altered because they only go to a size 2, which was a bit loose, but it was still worth it because total I still only paid 140 for a suit that I'm very happy with, and plus my tailor was kind of expensive.)
Also Macy's has a bunch of good stuff, unless you need small sizes, in which case you're better of trying elsewhere. When I went, they had a lot of good stuff in the 130-200 range.
