Amazon offers the Hitachi 18-volt 6.5" Cordless Circular Saw for $59 with free shipping. (Lowe's has it for the same with free in-store pickup.) That's tied with our April mention and the lowest price we could find by $11. It features a lightweight 6.2-lb. design, 6.5" blade, and 2" max cutting depth. Deal ends November 14.

Note that the battery is not included.
