Regarding the Bethesda New Year bundle, GamersGate has updated the description on the
product page:
==================================================
Notice:
Due to an error in our system the price for this bundle was wrong and lower than it should have been. The bundle offer have therefore been taken down, and is no longer available to purchase.
Because of the high demand and sale on this bundle we have run out of serials for most of the titles. We will not get new serials until middle of January next year.
If you want a refund for this bundle, please contact the support.
==================================================
So it seems that if you haven't revealed your serials already, you probably won't be able to for a while.
This information should probably be brought to the trading circles, to prevent frustration on part of the buyers.
