TK Maxx is almost exactly the same as TJ Maxx. I visited the store in Neumarkt, Cologne, which is about the same size as your usual TJ Maxx. The store contains a ton of clothes, shoes, purses, luggage, housewares, everything you would expect, and at reasonable prices. Most of the stores are about an hour away. You can find their addresses here.
