I don't have much experience with steam but I am usually with my friends in voice and they are always discussing about this but I think those people who offer games at less price than the steam one they usually purchase games on black Friday and other events.
That's how they get those games and then sale it a bit higher than they purchased in a sale

If you've read my previous comment you'll know that they change the country to get it for even cheaper price.
