There is also a sale at the HB store which still lasts for 1.5 weeks (likely +encore). GOG might head straight for the Winter sale which isn't bad from my point of view. With 10 days or 2 weeks minimum and ending after a weekend, that one would have to start Dec 4 or later that week. Weren't last year the deals spread on too many sales last year for most people tastes? Winter, Autumn and what else was it? Halloween?
