Cologne
Boots

It's funny: I've been shopping at Boots on and off for almost my entire life, and I never knew this existed until I stumbled across it on Basenotes! As a fan of both traditional eau de colognes and bargains (it's £4.39 for 400ml at the time of writing), I had to check it out. I found it in one of the larger of my local Boots, stocked with the women's deodorants. This mostly explains why I'd never seen it before, as I'm not a woman. I later splashed some on after a shower, and I was not disappointed. It was cooling and refreshing, and had exactly the faintly medicinal, citrus/rose/woody notes I was looking for. The smell faded away fairly quickly, but I expected that. I'm not going to pretend it's a truly exceptional cologne, but it's certainly exceptional value for money.
