Kmart again offers the Craftsman 20" Plastic Tool Box, model no. 273110, for $7.92. Opt for in-store pickup to avoid the $8.25 shipping charge. That's tied with our mention from two weeks ago and $16 under the lowest shipped price we could find for a similar Craftsman tool box. It features a removable tray, full-length metal hinge, and weighs 4.5-lbs.
