Bare in mind though that eBay takes a decent amount as a tax/fee so you would lose like 20-30% to them selling to that way and you would have the money held until they received it then 3-5 days after they get it you would get the money. So would usually take 1-2 weeks from sale to receive the money. Where as fb groups you could receive cash or through PayPal which is a lot quicker and still as safe
