In 2014, for a course that teaches students teamwork, I bought 20 sets of basic lego bricks for a bridge building exercise. The cost per set was 20 Euro. This year the number of students in our project courses exceeded what could be done with this basic set of legos and so I looked to buy more.
Two years later, the cost of these sets has exploded to more than 100 Euros per set. Mostly that’s because (a) the actual set was retired and (b) there is no proper replacement, just new “classic sets” that come with lots of pieces that nobody wants. I sense a bubble in the Lego bricks market… divest yourself now! Send them my way!
