I bought two of those on 8/30/23 for $230.63 each, or $10.48/TB. As I mentioned above, get Keepa or TheCamelizer & you'll see the price history there. You can also setup price tracking, notifications, etc.
That's $100 more than what I paid for it not that long ago. Get a price tracking app. I prefer Keepa, but CamelCamelCamel (aka the camelizer) should work well also.
Get the "Keepa" browser add-on / extension or cell app for Amazon item price tracking. It'll show price history right there on the item page, & you can also setup your own price tracking & notifications. A decent alternative is "The Camelizer" aka "CamelCamelCamel," although I prefer Keepa. The best $/TB I've seen for a new HDD is the 22TB WD Red Pro. I bought 2 not that long ago when they briefly went on sale. Keepa will show the price on the graph & I think in statistics, or something similarly named.
