Most of the weapons and equipment in Counter-Strike have had the same prices since the day the game was first released. These prices greatly affect the overall balance of the game. We at Valve know we're not alone in thinking that some of the prices in the game have never been exactly what they should be. (Uh, night-vision?) But rather than tweaking the values ourselves, we thought we'd rather let you decide. Coming soon in Counter-Strike: Source is a new system that sets the prices of what you can buy based on, well, what people are buying.

Starting on October 11th, the prices of weapons and equipment in Counter-Strike: Source will be updated each week based on the global market demand for each item. As more people purchase a certain weapon, the price for that weapon will rise and other weapons will become less expensive.
