Gifting PoF to another
To gift buy it from the GW2 web store or other Anet authorized retailers (if they offer pre-purchase) and once you get the game key you can it to give to the winner. Just don’t register it and don’t buy it through the in game store as the in game store automatically adds it to your account if you don’t have it already. Of course if you already have PoF on your account the in game store won’t be an option anyway.
A note on pre-purchase, if you buy it from outside Anet via an approved retailer make sure it is pre-purchase and not pre-order. Most sites I see right now are offering pre-order which would mean you don’t get the key until release day as opposed to pre-purchase that grants the key at the time of purchase. Really at this point you are best off buying directly from Anet to make certain you are getting the pre-purchase as the prices are the same as other authorized retailers. So there is no real advantage to buying it outside Anet unless for some reason you have to.
A last mention, if you have a favorite GW2 streamer/content provider check their information as they may have a referral code you can use. Once purchased via the referral code a small portion of the purchase price goes to the content provider so it helps support them.
