So much of what we buy is consumable (all the better reason to get a deal on it, right?) that it's nice to score a deal on something you very well could have for the rest of your life. Leatherman tools fit that description, so the Leatherman Sidekick Multitool for $27.37 at Amazon is a serious value and my no-brainer of the day.
