OK, as I have not received any mail like that I guess it is because my code was used by a friend I gave it to, probably they only sent the mail to people who's codes have not been used at least once.

That's a good question though, is my code still valid as I do have another friend who could not use my code this week due to insufficent cash error. I wonder if he could use it now if he manages to stash up enough of the good stuff before 10'th...?
