Walmart offers the Black + Decker 20-Volt Cordless Pole Saw for $57.10. The price drops to $54.59 when you opt for in-store pickup. (Amazon has it for the same price for Prime members.) That's the lowest price we could find by $31. It weighs 8.95 lbs., has an 8" cutting bar, and extends from 6.5 feet to 10 feet.

Note: This is the bare tool; no battery or charger are included.
