Ok quick update, 10 days passed for WoW HD to respond as of yesterday without a response and paypal have today ruled in my favour and are refunding me.
Definitely can't recommend them, if they'd let me know my order was refused and refunded me immediately I'd be annoyed but to make me file a claim and not even bother to respond is very worrying behaviour.
There shipping is fine, its there customers service that is terrible. Especially if something goes wrong. Just make sure you make payment with paypal and you should be fine. Please note they charge an additional 20% on top of there orders now.
Why not try deepdiscount when they have a discount on, They too charge 20% on top. Try Secondspin if your lucky they might have it.
