Walmart offers the First Alert Combination Waterproof Bolt-Down Fire Safe, model no. 2087F-BD, for $105 with free shipping. (Hayneedle charges the same.) That's tied with last week's mention and the lowest total price we could find by $24. It features 1-hour fire resistance at up to 1,700°F, is waterproof, and features four live locking bolts. It measures approximately 13" x 10" x 12".
