Everyone I know that had orders through Amazon have just had them cancelled by email as they are 'no longer available from the supplier'. Very dissapointing, obviously someone has silently pulled them and we are left second guessing. I think the gems from the in-game store are very poor value and I refuse to buy them, why would I want to pay more for less?
Tesco online are still allowing orders but with a 4-6 week lead time, I can bet you can guess the outcome of placing an order there!
