I think that’s where some of the confusion lies. For McClelland tins we see a general range of prices but average is about $1/gram. The OP’s posted example was well above this price at $2.85/gram. Or $285 for a 100g tin. Maybe someone is willing to pay it but thats not market price.It's the market price for the item.
Sure I'd like to get my hands on some Balkan Sobranie 759 but the market price is way outside my buying ability.
This is different than the example because BS 759 has an established market baseline that is much higher than McClellands due to the fact that there is such a small extant supply.
This thread didn’t start as someone complaining about high market value but laughing at an extreme example of someone posting something for sale well above market value. It’s gone off the rails since then.
