youre better off buying it for like $20 from an online cdkey store... might be like $5 more buying it online than here.. but its also 100% safer.. since account wont be retrieved by whoever sells you the cd key
you have a point, but im more willing to trade, b/c i have a half life 1 vacced acc, and i bought css for one acc, but my friend wants to play on the hl1 vacced, so im planning to get a key online, if someone has =/
