Walmart offers the Greenworks 40-volt G-Max Cordless Lithium-Ion 20" XR Dual Action Hedge Trimmer for $33.23. Opt for in-store pickup to drop it to $32.90. (Amazon charges the same for Prime members only.) That's the lowest price we could find by $27, although we saw it for a buck less last week. It extends to 6.5-feet and features up to 3,000 strokes per minute and a cut capacity of 5/8".

Note: A battery and charger are not included.
