UK based here, ordered at 12 got the email at 4:30.
It could be that the orders might be getting cancelled because of the fake addresses, or people might be using the same address on multiple accounts.
I have a GAME reward card which I linked right away, didn't have an account before as I only shop at sopto.net. Didn't have much in the card though, around £5 but didn't know how to include that with the purchase. XD Ah well, still a good deal for someone as broke as me. I've got almost everything that is currently up for grabs but hopefully we'll get something good that I don't have in the future.
