The containers! Oh the containers! Dear sweet lord, the containers!
Just being in this place feels like a joke. The concept of the store seems absurd. But once you get beyond the weirdness and embrace the idea, this place is pretty amazing. It's like a Target store just filled with containers. Big ones, small ones, even little bitty ones. It will pretty much have what you need to keep your stuff organized.
The Container Store also does a good job with ideas of how to organize your space. They have lots of displays, showcasing ways that you might organize your garage or office or kitchen. It's not as chock-full of ideas as an Ikea showroom, but they can get you inspired (to buy their stuff and organize your house with it).
