I can't find out where to turn off notifications of sales for games. I keep getting notifications for games I already own.
you can do it individually, but to do it by default, go to the sub preferences and in the "Include in subscriptions (defaults)..." column in the "Items" sub-section, uncheck "Items For Sale" and probably "Ebay auctions" as well. And don't forget to click Save
Here is the direct link to the subs prefs page: /subscriptions/prefs
