Boots' fragrance gift sets are up to 50% off across the board but the 212 Men set gives you a deodorant spray as well as the EDT - the deodorant goes for £18 on Amazon, rarely any cheaper than £16 anywhere else so you get the 50ml EDT for a couple of quid on top.
One of my favourite fragrances (though I'm sure everyone will pile in with their olefactory opinions) and a stonking bargain at this price. When used reasonably, the deodorant can last a few months.
Both in-store and online at boots.com
EDIT: Don't forget up to 5% ish TCB or Quidco for new customers, 2.5%ish for existing
