Big Dan mentioned it on the ToolGuyd Forum, and I would swear someone sent me a direct link via email (sorry, I can’t find it in my inbox to thank you personally): Buy a Dewalt 20V Max outdoor power tool kit, and get a free 3.0Ah battery pack.
Eligible kits include Dewalt’s air blower, string trimmer, and hedge trimmer. The first 2 cordless brushless outdoor power tools were previewed here last year, the hedge trimmer is a newer addition to the line.
Your best bet is to go to the deal info page, linked above, where they ask you to select the desired power tool and free battery to be added to your cart at once.
Adding them separately works as well, just be sure you select the products where Amazon is the direct seller.
Deal ends June 30th, 2016.
I’ve only tested the blower thus far, and like it a lot actually. It’s a great size and weight, has plenty of power, and is easy to use, I also like that it has a built-in stand for placing it down on flat ground. It’s quick to just pick up and use.
The free battery is a lower capacity 3.0Ah pack, but if you were thinking of buying one of these kits anyways, you could hardly complain about the price. I’d consider that 3.0Ah pack to be a spare, for those times when you forget to recharge the included 5.0Ah pack and it only lasts half a task.
