Question

Electronic commerce

Hello everyone
There is a service plati.ru, which offers a huge number of different keys to games at lower prices. Such a question, where do sellers get the keys to Steam games? And if there is a legal way to take them at a reduced price?

Answer 1

Games in the form of gifts (steam gifts) are obtained through automated farming of cards (see ArchiSteamFarm, etc.) or items and their subsequent sale on the Valve marketplace. To withdraw money from the sale of cards / items, they use the purchase of the game and its resale in the form of a Gift.
