I reviewed your profile and your ad. Here are my thoughts.
1. You’ve only been a member for three days. New members when buying pins have a expectation that when they buy a pin the seller will help them with repairs down the road. Not true. Part of this hobby is learning to do your own repairs.
2. You’re wanting to pay what I think is a reasonable price for a 7 year old pin, but because it’s a top 10 pin in most polls, most people want $6800-7000.
3. Since the pin in question is in high demand, why would I as a seller want to sell at a low price to a new buyer when I can easily sell to fellow local collectors who’ll pay cash and you want to pay via PayPal or other online payment.
4. Change your ad and say that you’ll be willing to pick up within x miles.
5. Find pinball locations near you that are open and visit them. Meet fellow pinheads and start networking.
6. When we’re past covid pinball leagues will start up again. Join a local league as it’s a great way to network. Most pins are sold by word of mouth, not on CL, FB, etc.
7. There’s a local seller in Atlanta with a Metallica Monsters premium for $6900. If you’re willing to pick it up in person and pay cash on the glass I can put you in touch with him.
