I can buy PC for 12 USD? That's a totally crazy idea.
For that much for sure I can't buy many games, access to numerous movies and TV shows, additional Twitch sub and I don't know what else they have. Frankly the Amazon store is the least important thing to me in this package.
Oddly enough I still might not get it, as that company definitely has become pretty fucky.
Americans have more propensity to consume than Poles. Amazon sees this and prices accordingly to maximize profit. It's the same reason why games were sold in Argentina for $5 when they were $60 in the US.
