That's a 389% price hike, and a bit unfair on actual Argentinians.

That price then shot up to 2100 pesos overnight (which is about 30 USD). As reported by VG247, when Steam first opened preorders in Argentina, it cost just 539 pesos, which is only about 7 US dollars. After its PC release date was announced, there were loads of reports that its price across various countries was fluctuating due to people using VPNs to buy it. Most recently this happened with Horizon: Zero Dawn. Those who use VPNs (virtual private networks that let you get around geo-restrictions and, say, pretend you're using the internet in France) have taken advantage of this in the past to get their games for extremely low prices, which, in some cases, has forced publishers to up the price of their games in those low-income countries to stop people from doing that. Regional pricing on the storefront is done so that lower-income areas can get games cheaper. While this might immediately look like a bit of greed from Steam, it actually goes a bit deeper than that.

Valve has recently made changing your store country more strict, which requires completing a purchase using a payment method from that country.
