Make sure you read the description properly...
I am completely happy with this product, considering with the 5% off i paid around 35 pound for battlefield 4 premium. But, do not fall into the trap i did of not reading the description properly, as this is in fact not a code for the battlefield 4 premium and is actually a 40 pound gift which goes into your Microsoft account. So basically, i paid 35 quid for a 40 quid gift card, which i could of spent on anything. Free money ftw!
