Can you buy CS:S by itself w/o HL2?

[Mo0o]

Trying to find out if I can purchase as bday present for friend. Can't check on my Steam since I already have the game

Over here, CS:S bundled with DoD:S (Retail Box) costs about US$60.

I'm pretty sure you can if you buy it directly off steampowered.com:

you can buy only cs source for $20.

Tho I like the total HL2 package with everything, for someone on a budget looking for years of MP time, DoD:S or CS:S is easily the best $20 you could spend!!
