:/
I used eneba just now, it cost £18 and pennies when paid by credit card. I don't even need/want premium but thought I might as well since I have quite a lot of plus stacked.
I've used gamivo xblg > gpu. They did sell out but still sold stuff to me in the past, but the refund did eventually go through.
Did they give you the code right away? I used PayPal on the other two and they are both "pending" despite having taken the money from my PayPal account.
