WD External 10TB for $159.99 after instant promo code & limit of 5x (I'm guessing per household/customer) from NewEgg. Going from Friday 02/21/2020 - 02/23/2020 (I believe PST too).

Happy huntin' as they say...
P.S. My old Seagate rep told me years ago that they pay upfront for the warranty period of the drive to a 3rd party company that handles the RMA process (even if it seems fully internal to the company). So that may be part of the reason why the externals with short warranty periods cost less & why they aren't covered under warranty if they are "shucked".
