I've been keeping an eye on ryobi batteries. The $99 deal for a 4ah battery and charger is one of the best value deals I've seen in a while.
Noticed a new kit on the bunnings website recently, it's not logged on price hipster so I assume it's a new kit.
If you're in the need of a drill and impact driver, this is honestly a killer deal. I paid $200 just for the skins, so the way I see it, you're getting at least another $99 worth of value.
Makes a great Christmas present for your pops too :)
