Walmart offers the First Alert Combination Lock Waterproof Bolt-Down Fire Safe for $99 with free shipping. That's tied with last week's mention and the lowest price we could find by $22, outside of the mention below. This safe claims to be the only safe that can be bolted to the floor and remain waterproof and fire resistant with the warranty completely intact. It measures approximately 18" x 15" x 20".

A close price: Mills Fleet Farm has it for $104.99 with in-store pickup.
