There is another site that sells Steam game keys in bundles for cheap! But, I have to say; this may be the best price offer I have found. Gamebundle's website deals include extra boosts, like BundleBlitz, which typically occurs during the last week of the bundle sale.
BundleBlitz is when you purchase the bundle, as a gift, you will receive two codes for each game instead of just the one that you purchased, at no extra charge! You can always gift these codes to yourself as well.
The bundles are offered in an overlap of the previous bundle, giving you more than just one bundle of games to choose from. The bundles are sold in a "Pay What You Want" form, which means that if you only pay $1 then you still get two games. It differs with each bundle on the minimal amount to pay to unlock all eight to ten games offered in the bundle, but is almost always less than $4. The amount minimal will always be $1 for two games, but the minimal price for all games is based on the average amount paid for the bundle, plus 25 cents.
It's an amazing set of deals that is offered and you can also get daily sign in prizes!
