Walmart offers the Stanley 4-in-1 Pocket Screwdriver, model no. BOS66344, for $2.79. (Amazon offers it for the same price as part of its add-on program.) Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. That's tied with our mention from a month ago and the lowest price we could find by $3. It includes two double-ended bits in sizes 5/32", 1/8", 1PT, and 2PT.
