Walmart offers the Stalwart 45-Piece Cordless Screwdriver Set, model no. 75-PT1000, for $18.73. (Amazon charges the same for Prime members.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's a buck under our February mention and the lowest total price we could find by $23. It includes a screwdriver with LED work light and flashlight, charger, and a selection of bits.
