The Container Store -- Folding Crate
I got this in college which was ... well, let's just say a different president was in office, and I STILL use it every week. In fact, I bought a second one of them because they are so useful. Its supposedly a laundry crate, but I have used it for storage, for quick transport, and just about everything. They fold flat, and then pop out like magic when you need them. Tuck away for easy storage, out of sight, out of mind.
