You could try just contacting them and asking when they expect a restock.

Someone else already mention serverpartsdeals, I’ll go ahead and add on to that. They have manufacturer recertified HDDs as opposed to seller refurbished drives. Avoid refurbished drives. I have a dozen drives from them ranging from 8-18TB and yet to have one fail, the older 8TB drives being maybe 8 years old now. Reach out to them and find out if they are going to have any more holiday sales - I’ve found better deals better than Black Friday on electronics well into December.

they generally refer to archives of specific websites that would be good to keep in case of an apocalypse

They probably have a price bot/algorithm that tracks prices elsewhere and adjusts their prices to trend the same.

Black Friday has mostly been a scam for a long time now. Companies have low stock on the good items to drawn you in and sell you the crappier stuff that they’ve got a bigger margin on. I’ve found as good or better deals throughout the year compared to BF/Cyber Monday.

As someone else mentioned serverpartsdeals is good to go and has probably the best pricing along with really great packaging for drives.
