Walmart offers the Tekton 135-Piece Ratchet Screwdriver Electronic Repair and Security Bit Set for $28.55. Opt for in-store pickup to avoid the $5.99 shipping fee. (Amazon charges the same price with free shipping.) That's a buck under our March mention and the lowest price we could find by $5 today. This kit is specifically designed for repairing mobile phones, tablets, laptops, computers, game systems, wristwatches, and eyeglasses.

Update: It's now out of stock at Walmart; however, Amazon still offers it for $28.51 with free shipping.
