Had no problem to buy SPL TD, just that I had to retry and choose another 'second' 4-digit number, the one on the backside of my card.
I hope you will get your stuff, at the reduced price, you should.
I was not alowed to buy the TD before the very start of the TD offer, coz the auto-selling computer can handle just one price per product at a time.
It would be rediculous if this would be the reason to refuse you the special price after 31 dec.
But I think CW will get to you

Anyway, my support, for what it's worth, is promised!
Keep us informed.
