Home depot has many of the makita 36v tools on sale (~ $100 – $200 off ) that can be combined with the extra batteries promo for a real slick deal.
For example all kits below come with 4x batteries:
$400 Makita 36v 10" miter saw xsl06pt : Reference Only
$250 Makita 36v worm drive style saw: Reference Only
$250 Makita 36v Recip Saw: Reference Only
Impact & Drill kit also on sale, but didn’t pick that up.
Looks like it’s in store only, as prices online are not reflecting the deal.
