Looks like a good price on the Bosch Hammer Impact Drill UniversalImpact 800 (800W, in Case).
German-Engineered, Hungarian-made.
All the way down from $109.59 to $54.90 delivered (don't have to be an Amazon Prime member).
Cheapest on eBay is $83.89, but can't find much of it elsewhere.
Competition at Bunnings at this price level is fairly limited. Note the Bosch Green is the DIY line, while the Bosch Blue is the tradie/professional line.
No idea when it ends - check out the other Bosch gear on sale as well.
EDIT: Just note this comment.
800 watt, in case of what? In case of emergency?
