But wait! There's more!

As usual, there are packed goods for those who like to own everything, including game packs from Valve and PopCap.

Surely there's nothing else that could get you even more psyched. Right?
Well ... there's something that might be worth mentioning. Flash Sales and voting for the next game you would want to see on sale.

If you check out the Steam store, you will notice a vote featuring games one of which might be the next on sale, depending on user feedback.
Certain games are also featured under Flash Sales. These are timed offers, not related to the daily deals so be sure to check back frequently to not miss out on the good stuff.
