a storage option -- storage by mail
I haven't used it, and so I know nothing about how well it works. But, this looks like an excellent short-term solution for anyone between addresses for a short period who doesn't want all their stuff immediately. Basically, you ship them your stuff, they house it in their secure warehouse, and then they ship it to you anytime you want wherever you are. You're paying for the shipping as part of your storage fee, and since we are part of the U.S., no extra charges as far as I can tell.
Something like this could be ideal for those who are just making the move and can't decide whether they will really need X -- box it, store it by mail, and have it shipped if you need it. No need to impose on family or friends stateside to ship it to you, or to travel back to get it out of your storage unit.
