HOT purchase
If you want to buy it for someone else you have to buy it through buy.guildwars2.com or some other authorized retailer. When you buy it from the GW2 website you will receive an email with the serial code and instructions. You can then send that to your friend to use. Do not register it yourself, let your friend do it. Do not buy it through the in game gem store as that automatically updates your account and you will not be able to gift it. If you have already upgraded yourself I don’t think you will have that option anyway.
