Hi guys,
Many of you astute younguns may already know this, but if you use a Chrome browser plugin Enhanced Steam, you can quickly see the historically lowest price and current price on a variety of sites, for all steam games.
Here's a link to the free plugin. http://www.enhancedsteam.com/
Best thing to do if you don't have a lot of money. I use it, and I have a lot of money because I am wifeless and have no younguns.
