Seems like this set is discounted with few sellers at the moment. Don't know for the duration for these sales.
Set is still worth the build I think though might be making way for 2021 sets. Not a bad price. Have got one myself, got it off the Christmas sales for pretty much this price and enjoyed every minute of the approximate 4 hour build. My son has enjoyed playing with it as well. Lots of little details; winch, roof rack system, low range gearbox, 4-speed sequential gearbox, few little fun details under the bonnet such as extractors and airbox. Cylinders/pistons bouncing around as per normal on LEGO sets and independent suspension front/rear.
Just note the instructions on drivetrain set up as might get clunky whilst in gear and another little grey bit near the rear differential can easily cease the whole drivetrain if fitted incorrectly by accident.
Might not be the lowest ever but in the ball park.. And might get even further discounted in the future, who knows..
Enjoy!
Oh forgot to add and couldn't edit the post; WA Innaloo store had them on the shelf (6) for the same price so website might have inaccurate information (online only)
