Keep in mind that not everyone has access to the USA Amazon, and other markets have such "specialty" lights for much higher prices in general.
For example, Amazon Germany has the MT10C, without any additional items aka battery, for around 72 Euro, not including shipping (with shipping it can go as high as 90 Euro, depending on your situation):

That's a grand total of around 98 USD compared to the Massdrop price.
