Cheapest I've seen this monitor on eBay and cheaper than Amazon has ever been according to CamelCamelCamel - https://au.camelcamelcamel.com/product/B07XBQ2XMK

Great monitor, got it last year amidst the early days of COVID and paid much more. Colour, G-Sync, brightness or viewing angles all great.
But that new Dell 27" that's always on sale is probably better value as it's regularly on sale for much cheaper with the same specs.
