The Amazon US tech deal keep coming.
These are $139 to $149 plus postage locally.
Not sure what non-prime postage would cost, probably better off spending the $7 monthly subscription or free trial
They were cheaper in USA earlier in the year but still good price for a premium, well rated and fairly quiet cooler. (Not speaking from personal experience)

Can also try Newegg for $102.49. https://www.newegg.com/global/au-en/noctua-nh-u14s/p/N82E168…
I expect the $10 off App code will work (got entered to my post automatically)

Probably only because no one buys this model, as it's now 7 years old. At that price, just get the NH-D15 or NH-D15S if your tower can fit it.
