Lol what, garry's mod is a daily and is 2.5$ in US, and 1.5$ in Ukraine and other CIS countries. And you can get source for same price as well in sale. Now do the math.
Like I said, garry's mod is on sale. Plus, CS has been sale a lot of times earlier with 75% off. So some people do stock them in inventory to trade later, and this is what I'm looking for.
