When ending a MarketPlace listing successfully, Pinsiders can invite user feedback from the other party. Marketplace feedback cannot be removed, but can be responded to by AntennaMan.
New! It is now possible for any Pinsider to leave feedback, without an invite. There are some checks in place to avoid abuse and "fake" feedback.
“Jeff is fantastic all around. Negotiations were pleasant, he was excellent in his communication, and the guy just loves pinball. His pins are as-described, so worry not if you can’t see them in person. Will do business with him again!”
