I was very skeptical looking at the reviews here, but I decided to order Halo MCC anyway because the problems seemed to be with FIFA coins.
Have to say the speed of delivery was INSANELY fast. As soon as I confirmed the payment and opened my e-mail my receipt, order confirmation and Game activation code was delivered. Felt I had to do a positive review in light of the amount of negative reviews here.
TL; DR:
10/10 instant delivery.
