Sentry In-Floor Safe

There are plenty of different places to hide your most valuable belongings, but in the floor normally isn't the first place you'd think of. The Sentry In-Floor Safe ($120) can keep 540 cubic inches of stuff protected, with a four-number combination lock, waterproofing, and installation in a place that your average thief isn't going to check — like in the floor, underneath a couch and rug.
