It works, but I am posting it as YMMV
because this is a Amazon promotion mistake!
Dewalt has a Buy 2, get 10% off and Buy 3, get 20% off promotion going on through several retailers, including Amazon, CPO, etc.
However, Amazon's promotion is broken. It is currently allowing the discounts to STACK, meaning you get 30% off the tools order if you buy 3 tools.
No coupons required. Promotion is applied automatically at checkout.
Double check before you click "Place your order"!
User dogi pointed out that It also stacks with the Buy Batteries and get two free tools promotion if and only if you choose the bare tools that overlap.
The BEST bang for buck comes if you buy the DCB205-2CK Battery Kit [amazon.com] and at least TWO from this list (or 3), and then any one tool from the buy 2 get 20% promotion (jump to the 2nd list below). So total of 1 battery kit and 3 bare tools.
In other words, buy ONE of this:
DCB205-2CK Battery Kit [amazon.com]
Plus at least TWO of these:
These tools (and only these tools) overlap because they are part of the buy 3 AND the battery kit promotion.
DEWALT DCS331B 20-Volt MAX Li-Ion Jig Saw [amazon.com]
DEWALT DCS387B 20-volt MAX Compact Reciprocating Saw [amazon.com]
Dewalt DCG412B 20V MAX Lithium Ion 4-1/2" grinder [amazon.com]
DEWALT DCS355B 20V XR Oscillating Multi-Tool [amazon.com]
DEWALT DCF883B 20-Volt MAX Lithium Ion 3/8-Inch Impact Wrench with Hog Ring [amazon.com]
DEWALT DCGG571B 20-volt MAX Lithium Ion Tool Only Grease Gun [amazon.com]
DEWALT DCF620B 20-volt MAX XR Li-Ion Brushless Drywall ScrewGun Baretool [amazon.com]
DEWALT DCF880B 20-Volt Li-Ion 1/2-Inch Impact Wrench Kit with Detent Pin [amazon.com]
and ONE of these if you still need another tool.
Here are some tools that works for the 30% off but does not stack with the battery promotion. This is my best attempt at a complete list. Unfortunately I cannot be certain because Amazon did not publish their list.:
DEWALT DCS361B Sliding Miter Saw (Bare),7 1/4in [amazon.com]
DEWALT DCD740B 20-Volt MAX Li-Ion Right Angle Drill [amazon.com]
DEWALT DCN692B 20V Max XR Brushless Dual Speed Nailer [amazon.com]
DEWALT DCS380B 20-Volt MAX Li-Ion Reciprocating Saw [amazon.com]
DEWALT DCF899B 20V MAX XR Brushless High Torque 1/2" Impact Wrench with Detent Anvil [amazon.com]
DEWALT DCS551B 20V Max Drywall Cut-Out Tool
DEWALT DCF897B 20V MAX XR Baretool High Torque 3/4" Impact Wrench with Hog Ring Retention Pin Anvil [amazon.com]
DEWALT DCF885B 20V MAX Lithium-Ion 1/4-Inch Impact Driver [amazon.com]
DEWALT DCD985B 20-Volt MAX Lithium Ion 1/2-Inch Hammer Drill/Drill Driver [amazon.com]

DEWALT DCF889B Bare Tool 20V Max Lithium Ion 1/2-Inch High Torque Impact Wrench with Detent Pin
DEWALT DCS373B 20V Max Lithium Ion Metal Cutting Circular Saw
DEWALT DCS371B 20V MAX Lithium-Ion Band Saw, Bare-Tool
Attached is a picture of my checkout page where you can see the discount of 20% AND 10% stacked.
Another picture shows this 30% discount stacked with the 20v battery promotion.
Good luck finding the right combination of tools before Amazon corrects the mistake. GO!
If you only care about the 30% off tools discount, you can also buy multiples of the same tool, and you get 30% off all of them.
For example, you can buy FIVE units of DEWALT DCS387B 20-volt MAX Compact Reciprocating Saw for $517.90-$103.58-$51.79 = $362.53+tax
