I may have worded my comment poorly and in an exaggerated tone since used copies can be found on vinted/ebay in between 35-45 (I was thinking about typical mall retail stores), but that's still an incredibly steep price for what's probably one of the most sold - thus widely available - games on the platform. The "all time low" isn't really a good indicator, either, as others comments pointed out: just because a product gets a deep discount, once, doesn't mean everyone is ready at that exact moment in time and space to hop on it and buy it.

A used price from reputable sellers (meaning, stores who can provide some sort of warranty) of 50-60 is just batshit crazy for a used ten years old game.
