DEWALT 20V MAX XR Impact Driver kit with two extra 5Ah Power stack batteries $309 at Acme Tools

This kit includes the DCF845 impact driver kit, which comes with two standard 5Ah batteries (DCB205), but it’s bundled with two extra Powerstack 5Ah batteries (DCBP520). That bundle is $349.
With the "YELLOW" promo code that Acme is running that comes out to $309, and for an impact plus four 5Ah batteries that seems like a pretty good deal to me.
