JLCPCB seems too good to be true

This is a curious business strategy... in most markets, bulk discounts mean that products and services are cheaper per unit when you buy more of them. These PCBA vendors are creating a market where the unit price increases as you buy more. That will attract lots of little orders, but I think it may frustrate larger customers. Or else large customers will demand the same pricing as smaller ones, or they'll split up their larger orders into multiple small orders.

Yeah it's an interesting conundrum. I end up doing one of two things:

Ordering 10 boards repeatedly, because 20-50 is more per piece on the site.
Ordering 100-200 boards to get close to the same price/pc as the prototype 10 piece special. At a certain point increasing quantity does start bulk discounting, but the price jump from 10 pieces to less than 100 is currently a huge crap shoot.
