Walmart offers the Hyper-Tough 57-Piece Plumber Tool Set for $11.92. Opt for in-store pickup to avoid the $5.99 shipping fee. That's the lowest price we could find by $3, although it was a buck less in September. (Most stores charge over $22.) It includes a pipe wrench, groove joint pliers, mini hacksaw, hose clamps, tube cutter, basin wrench, Teflon tape, and washers.
