Hayneedle via Walmart offers the Hopkins 2x4 Basics AnySize Workbench Kit with ShelfLinks for $46.54 with free shipping. That's the lowest price we could find by a buck, although we saw it for $2 less a week ago. 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.
