The Amazon Treasure Truck has the Star Wars Droid Inventor kit for $59 today (40% off retail), Lowest price I’ve seen for a pretty popular toy this holiday.
To order this, you will need the Amazon app.
On the iOS version (not sure if it’s the same for Android); go to Menu > See All Programs > Treasure Truck.
Once you order it, you’ll have to pick it up from the truck by a certain time (usually around 8:00pm local time).
