Ok, well it hasn't worked for me, my card was declined, so no order number other than the payment reference on my statement- payment was still taken and a week later I am still out of pocket. To me that isn't a 'valid' payment method, but I suppose it is possible I am the exception, not the rule.
It's only $10 but still very annoying and it still hasn't been sorted. I keep checking as I want to watch something!
