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.
