Are there any reliable online traders/businesses that I can sell my used electric appliances to?

I’m not talking about auction sites like eBay! I mean the ones that simply calculate the value of the item I’d like to sell and sends me a check after it’s been shipped and recieved.
Some of the things I would like to sell are-
Desktop Computers
Monitors
Electric hair-care products (E.g. Straightening/curling irons)
Electric kitchen appliances
Handheld games (E.g. Gameboy)
Old landline phones
Power tools
Old game consoles (E.g. SuperNintendo)

No.
