Home Depot offers the Ryobi 4-volt Lithium-Ion Screwdriver Kit, model no. HP54L, for $39.97. Opt for in-store pickup to avoid the $5.99 shipping fee. That's tied with last week's mention and the lowest price we could find by $20. It features a tri-beam LED light, forward/reverse switch, two-finger trigger, and two-speed gearbox.
