css from local stores are same price with the normal price online, but sometimes steam make a good deal with games so i suggest to buy a copy of css game via steam specially this momment its on half price. you can create steam account for free and just add the games later, if you have sucks internet connection use the 4 cd's came with the box but you have to update it after. if you inserted the cds use your existin steam account for you to not make another one
