A single DEWALT POWERSTACK 20V 5Ah battery is selling close to $100 currently on Amazon. With this DEWALT deal you get the battery and charger for the same cost of a battery alone. This is a trend we are seeing more of.

There's been more discounted batteries in the market, likely due to the decrease in lithium prices lately from over supply. We are also seeing BOGO deals, like this Bosch Buy 1 Battery Get 1 Tool free deal at Lowes.
