Just some extra information on the Steam Summer Sale:
Both Community Choice Discounts (You are able to vote on one of three available games, and whichever receives the most votes receives a discount) and Flash Deals only last for eight hours. Voting for a community choice disc. will award you with progress towards the Summer Sale Badge (There is also another badge alongside it, "Pillar of Community." Pack deals (also many individual games with an automatic 50% discount) will last the whole duration of the summer sale. After 24 hours, the "Today's Deals" will still be available the next day for 12 hours.
This may or may not be helpful, but nonetheless computerandvideogames.com released the whole list of "Indie Bundles and Other Bundles" in their link (Indie Bundles are sorted by day since they are included in Today Deals.)

If you want to learn more about the games featured in the daily list, then you can watch Totalbiscuit's (Channel is TotalHalibut) videos which as I said, basically details down all of the said games and gives you his overall opinion over whether you should purchase them or not. (I may have worded that a bit oddly :(. )

Last note: If you are hoping/waiting for a certain game to come under a flash/community pick but don't have the patience to wait for eight hours in front of your PC, then you can of course just use an online countdown timer, thereby notifying you of when steam gives new offers.
