RSS feed for major Steam sales? [closed]

Is there somewhere I can subscribe that would only show 40% off or more game sales? Steam is a must; bonus points for aggregating multiple sites/stores.

I'm rarely catching the sales on steam, and I imagine steam isn't the only company doing really nice occasional special sales.

Solution 1:

The Steam RSS news feed link is here. Steamprices.com also runs a variety of feeds based on your region and can also provide information on permanent price changes.

Solution 2:

http://www.cheapshark.com/ gives a good overview of different deals from different developers. Next to that there are several filter options, such as maximum price.

The browse page now has an RSS feed. (check the RSS icon at the bottom right of the filters)
