That's tough - the sale ended at 10 AM Pacific US time. It did say the ending time on Steam.
Yeah, I saw that afterwards. I was just checking all my DLC to see which I had, and waited for my marketplace listings to sell. Then was about to buy TOG, Celtic, Norse portraits and the Converter for 75% off, the sale was over. Now I have to wait a few weeks for the Christmas sale hopefully having 75% off on TOG.
