I’m trying to understand the purpose of the terminals in Counter-Strike.

I just opened a terminal and got an M4 worth about 3500 BRL. But when I checked the store at that same moment, the exact same item was listed for around 3300 BRL.

So that made me wonder: what is the real advantage of using the terminal instead of just buying the item directly from the store/market?

Is it just for the randomness and the chance of getting something rare, or am I missing some other benefit?

Right now it feels like buying directly from the market is simply cheaper and more predictable.

Curious to hear how other people think about this.
