I'm not in any way associated with them, even as a customer. I just learned about them from a web feed I get daily with new iPhone apps, which they are based around. As I understand it, you sign up, they send you a bag. You fill it and send it back to them. Then before your trip you go online, pick what you want from your clothes and send them your travel info. You suitcase meets you at your hotel. At the end of the trip you ship the filled suitcase back to them. They clean the clothes, and store them until your next trip. I'm fascinated by the concept and I would love to get feedback from anyone here with experience with it or even just your general thoughts on it. Here is their website. Thanks.
