Selling keys on eBay can be profitable if you can find enough. I am talking about just ordinary keys. Not the vintage skeleton and barrel keys, those can be even better.
At an auction a couple of weeks ago I bought a large jar full of keys for $10.00. Last night they sold for $81.00 sale price.
Perfect for crafting or what ever the buyer wants. I was happy with the price as was hubby. Next time he will be pointing out a large jar of keys instead of saying huh.
Have a great day, what are you selling on eBay that surprises you.?
