I ordered my orange box for $27.00 during a blackfriday promo. (damn thing just arrive today 12/7 however) But Orange Box is one of those title that worth buying every pennies imo. I usually don't have problem paying for titles that worth it...beside i'd like to see valve in business
as long as they keep pumping out such cool games.
If you only wants HL2:Episode 2, you may be able to purchase it digitally thru steam account also. But i'd get the orange box which comes with HL:Episode 1 & 2, Portal and TF2
