Walmart offers the First Alert 0.94-Cubic Foot Combination Lock Waterproof Bolt-Down Fire Safe for $100 with free shipping. That's tied with our mention from two weeks ago and the lowest price we could find by $36. 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".
