Walmart offers the Hopkins 2x4 Basics AnySize Workbench Kit with ShelfLinks for $48. Opt for in-store pickup to drop it to $46.83. That's tied with our April mention and the lowest price we could find by $6. You provide your own 2 x 4s and plywood to build a workbench up to 36" high and any length or width up to 8x4-feet. All hardware and instructions are included.
