How about a luggage tag vending machine in the airport?

You could try this entrepreneurial idea for about $100,000. If it works you could sell millions for $5.00 or $10.00 each.Full disclosure. I haven’t researched this very far. Be sure that others haven’t tried it. Test the price point. Could it be done as an App? So you design it, order it and pay for it on your phone. Then pick it up at the automated kiosk.

They will have to be durable, unique and easy to order.

I’m thinking $10.00 (maybe $5.00 if you have the Delta Airlines Ad on one side)
