To be honest, no. Not until you said it. I presume that, as a supplier, you know something? Have you asked them? Or are you just assuming because you've been able to get stock?
I'm not assuming anything as no one told me I can't order because I'm not in Asia.
Base on the lead time you provided, it sounds like those suppliers are ordering drop shipment directly from ESN
those have a 90 day lead time.
I don't order drop shipment (I don't do the volume, and the few percentage cheaper doesn't justify the cost of capital), and I keyed in my order to be sent from Korea HQ.
Or maybe there is something about Europe that I don't know about, but I am enough evidence to say its not Asia only
