Buying Xbove Live from Turkey via Eneba/Gamivo.

[iamanoob]

Having been gamesharing/GPU with my cousin on his account and it's due for renewal in the next few days, it's now my turn to buy. I want to take advantage of the £1 Gamepass trial on my dashboard so looking at 3 years of Live to convert it to GPU. Looking at prices just now works out around £25ish for a year of gold, so 3 years of GPU for less than £80.
Now question is are they reliable for the codes? Anything I should watch out for? Is paying by Paypal safer?

Thanks
