Walmart offers the Hopkins 2x4 Basics AnySize Workbench Kit with ShelfLinks for $49.46. Opt for in-store pickup to drop the price to $47.58. That's $12 under our mention from two weeks ago and the lowest price we've seen. (It's the best deal now by $2.) 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.
