As far as affordable places go, I like Marshalls, Ross, Rugged Warehouse, Nordstrom Rack, Plato's Closet, H&M, Old Navy, American Eagle, JC Penney, and of course plain ol' Goodwill
When I can afford it, I'm all about Nordstrom, Lucky Brand, and Saks Fifth Avenue, but it's been awhile since I could afford any of that.
I'll shop almost anywhere, really, and I own clothing items from almost every store (well, ok, there are a FEW exceptions

) - if it's cute, and I can afford it, I will wear it!
