Select Lowe's Stores have Greenworks Pro 60V String trimmer / Blower Combo w/ 2.0Ah Battery & Charger (STBA60B210) for $99.50. Select free store pickup where stock permits.
Note, pricing and availability for store pickup may vary by location. Consider checking other stores in your area if you see a higher price.
FYI on 2.0 Ah battery & usage: From reading reviews, there's no way you'll get 45 minutes from the blower, unless it's on the lowest setting... any moderate use of the "turbo boost" will net around between 11-13 minutes... & minimal use, 18 minutes on a good day.
