Spent $40 on a thermal leak detector for my apartment and it showed me exactly where my heating bill was going.

Found a huge draft around an old window frame I'd sealed with cheap caulk, fixed it with a $5 tube of better stuff, and my next gas bill dropped by almost $30, so what other small fixes have you guys found that actually pay off fast?

Wish I'd done that before my last heating bill murdered my wallet.
