As others have said, TJ Maxx can be hit or miss, but most of the time for me it's a hit. I buy most of my workout clothes here at great prices. I also tend to wear a lot of the outdoor brands (Mountain Hardware, North Face, Columbia, etc) and have scored some very good deals on clothes for my husband & myself.
It's a great place for kid's clothes, toys, & children's books. We have gotten many good deals on stuff for my toddler.
You do need to hunt around some to find what you want but it is worth it.
