Walmart offers the South Shore Basics Full Platform Bed with Molding in four colors (Black pictured), model no. 3070234, for $119 with free shipping. (Amazon charges the same in Black, Chocolate, Maple, and Pure White, although select colors are only available to Prime members.) That's tied with last week's mention as the lowest total price we've seen. (It's the best deal today by $16.) It measures approximately 75" x 54" x 10".

Note that the mattress is not included.
