Walmart offers the Hopkins 2x4basics Peak Roof Shed Kit for $50.50 with free shipping. (Amazon and Hayneedle charge the same price.) That's tied with last week's mention and the lowest price we could find by $4 today. This DIY kit includes instructions, a materials cut list, and 39 brackets to assemble a 7x8-foot shed.
Note: Neither lumber nor siding is included with this kit.
