Buying Video Games on Sale

Best way to buy video games is generally online. Having them online allows many people to track the price history of games automatically.

There are a few websites that allow for this price tracking:

Is there Any Deal

http://isthereanydeal.com
Compares the prices of multiple vendors and gives a lowest and regular recorded price from these vendors. It provides a useful way of knowing whether the steam sale is actually worth it, or if other vendors have offered it lower.

Steam Prices

http://steamprices.com
Allows you to see a price history of steam games over a period of time. This is useful for knowing if the sale that is on now is actually a deal, or if it just seems like a deal because it's the holidays and it "should" be.
