Acme Tools has a promotion which adds a 4.0Ah battery to this bare tool. Promotion expires June 30, 2019.
I have been watching for a deal on a full size Dewalt cordless saw. $129 seems to be the standard price at B&M but I have not seen the battery add on. Though not as adaptive as the Flexvolt DCS575B, this is a highly rated saw.
