Home Depot has lowered the price of the Rigid GEN5X 5 piece cordless combo kit. It was $499 and is now $399. It says "New Lower Price" so I believe this is a permanent price drop. They have lifetime warranty’s just make sure you re-register them every time you get something replaced, especially the batteries.
It was pretty popular it was at this price.
