For anyone who missed the Dominos Pizza Deal a while back. This gives you all the expansions for PS4 and comes with a cloth banner - which you can see on the store page that's linked.
Ozgameshop has it for a similar price without the cloth banner but you'll definitely need to pay for delivery and wait an extended amount of time - since the games usually need to be shipped from overseas
$49 for the PC version.
I can recommend this game. It was my first MMO and I loved it. For the price, you get a lot of content.
Just remember to factor in the ~$15 a month subscription fee. You get your first month free.
