Basically, if you need peps better order now because you are probably not receiving an order (in the US) until late-Feb, early March.
From the Fishsteak lover Tracy himself (and in the OP):
The Chinese new year holidays will start in mid January, and it's a 15+ days holidays, when all shipments are paused because the logistics companies are fully closed, production stops, and my assistants will go back to their families to spend time with, so is the case of every chinese source, and you've seen how it looks the past 2-3 years. We advise you to make your orders earlier, during the next 3 weeks, you've been warned about the CN holidays, plan in advance!
From the Google:
