I think, tragically, the blog post has caused this price increase.

The offers on Amazon are most likely all drop shippers trying to gauge a price that works for them.

You might have better luck ordering directly from China for a fraction of the price: https://detail.1688.com/offer/836680468489.html

AliExpress sells them, too, which is much more accessible for anyone living in the EU.
