I’m sure his has been said many times already but here’s how you order from them:
EMAIL ONLY
ask them to set up a customer number.
Once set up, always have the parts guides from PPS handy. They want you to have part numbers when you order.
If it’s a gottlieb game, I just tell them the game, and the parts I need if I don’t have the parts guide or manual. They are good with that.
They send an email back confirming what they have or don’t have, with prices. You confirm, they confirm and mail the stuff to you.
Once you receive, mail a check back to them.
