Beware when you sell anything worth more than 100 dollars, record serial numbers and decline the sale before shipment if you suspect a bad Buyer. There Are scammers who buy and lie on this market place and Mercari will not help. I just got back a GPU that some amateur tech tried to bios mod and "Bricked" myGPU, Mercari sided with the idiot and gave him a refund. Do Not rely on this platform for long term or business selling. Maybe if you have some Junk laying around but not valueable items.
