Staples offers the Embassy Wall Clock with Hidden Safe, model no. JB4985, for $10.95. Plus, Staples Rewards members bag free shipping. (Not a member? It's free to sign up.) That's the lowest total price we could find by $10, although we saw it for a buck less last week. This safe allows you to hide valuables inside a working 10" x 10" x 3" wall clock.
