Figure 9 Carabiner

If you've ever had to move furniture (or anything else large for that matter), then you'll fully appreciate the Figure 9 Carabiner ($5). Sure there are numerous strap systems on the market, but most of them are ratcheting, and sort of a pain in the ass. With the Figure 9, you can safely fasten your gear using any available rope and not have to recall your Boy Scouting exploits to achieve safety in packing.
