Giorgio Armani makes quality colognes and this is a smashing price for one of their products!
Remember, this is the EDT and NOT the Aftershave. EDT's contain more perfume oil and thus lasts longer and are generally more expensive.
Go through Quidco for an extra 6.5% saving.
Edit: Price includes shipping
Oh wow, I just noticed that the 50ml version is even more expensive than the 100ml version. Bargain!!
