Well if you buy a 60 dollar new game then sell it and they only offer you like 20 dollars and they sell it for 55 dollars new that should be enough evidence.
I don't think you even know what the word "evidence" means, because hearsay, weasel word and your own baseless rambling are not evidence.
I wonder how fast you'd flunk law, journalism, medicine, criminal justice, literature, or literally any field involving research or citations.
