I know its been a similar price from Amazon USA but for people who may not like doing stuff like that this is ALMOST (thanks Jaystan lol) the lowest its been in UK.
Digital Deluxe also available at £14.99.
With all Ubisoft games they require Uplay, so you will recieve AC4 in your Origin Library but will also be required to load Uplay for activation before playing!
I have loads of Ubi games and its never once been an issue, its simply loads and dissapears.
Anyway, thought I'd share this!
*Whispers* "if your a savvy young scoundrel, you can get it for £8.80 if you set sail by the Indian Ocean"
See what I did there...... i'll get my coat!
