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 SNES.
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.
“Very helpful in understanding how to play the game, where the "bonus" points are, etc. Also helped with loading, and after the sale questions once I got it home.”
