Walmart offers the Hopkins 2x4 Basics AnySize Workbench Kit with ShelfLinks for $41.49. Opt for in-store pickup to drop the price to $23.56. That's a $24 drop from five days ago and the lowest price we've seen. (It's the best deal now by $16.) You provide your own 2x4s and plywood to build a workbench up to 36" high and any length or width up to 8x4-feet with a 2-shelf unit on top. All hardware and instructions are included.
