Sears offers the Step One King Platform Bed with Mouldings, model no. 3070248, in Pure Black for $191.62 with free shipping. (Amazon has it for the same price.) That's tied with last week's mention and the lowest total price we could find by $11. This platform doesn't require a box spring and has a weight capacity of 500 lbs.
