CS:GO Is there a chance to be bigger sale?

No

Nope. Its a daily deal, its unlikely to go any lower.

Ok, but how often is there CS:Go sale? I can wait and safe that money and spend them more clever.

check to see the history

CS:GO will be 75%(if not 80%) off for sure.

Wait til Aug. 14, there will be ESL One Cologne and i'm 90% sure CSGO get ~80% off like last time.

cs:go Will probably go over 50% off, maybe not on this sale, but it will :3

i was honestly a bit shocked to see it only 50% considering its been way cheaper on steam

I am not sure if I should be happy or sad with that price. On one hand I was thinking about getting a copy or two to get some smurfs for fun, on the other everytime there is a huge sale on game it gets flooded by cheaters.

Wait until the last day of Summer Sale, if not, then it will probably be -75% on Autumn Sale.

During holiday sales I got it for a bit more than 2 €, so it should get lower
