They always have, but for parts they don't have in stock you must preorder (with a few days of lead time.)

Ah yeah, maybe it's easier than they make it seem, but I've found PCBWay preferable for small batch assembly because they just take a list of MPNs and give you back a quote, which is the service that I really want. Preordering etc. is detail that I don't really want to care about.

This is exactly what I like about JLC - the fact that some human doesn't have to be involved in the quoting process and that I can select parts from LCSC. The software handles everything.

Getting a human involved in quoting makes it more expensive and it gives these vendors an opportunity to BOM substitute for cheaper Chinese alternative parts.

		Totally fair that you prefer JLC's approach. There's clearly room in the market for different models. Part substitution is mainly a question of trust. As far as I understand it, you preorder parts through JLC's website, so JLC could easily automatically sub out your passives if they wanted to. For all that people worry about this a lot, I'm not sure if the incentive to do it is really there for shops like JLC or PCBWay. The components that are easy to substitute are cheap anyway, and these companies can easily just pass on any additional cost to the customer. I'm not personally going to haggle with PCBWay over a few additional pennies for a chip resistor or ceramic capacitor, given that the entire service is mind-blowingly cheap.
