Ross! Since it's hard to look for things to buy in Ross, it's a very nice surprise when I spot something I really love. It's like a treasure hunt. I can spend hours in Ross and it can be fun. The most I spend in T.J. Maxx or Marshall's is about 20minutes.
Depends on what I'm looking for. Shoes, I got to Marshalls. Bags, I go to T.J. Maxx. Clothing is a crap shoot - I find stuff at both from time to time. I don't generally go to Ross, though, because it tends to be dirty and not well organized.
