Walmart offers the Black + Decker 3.6-volt Cordless Rechargeable Screwdriver and Project Kit for $29.91. (Target charges pennies more via pickup.) Choose in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $13. The screwdriver features a forward and reverse switch, 3-position handle, and spindle lock. The project kit includes 39 common hand tools and accessories, plus a carrying bag.

Update: It's now out of stock at Walmart; however, Target still offers it for $29.99 with in-store pickup.
