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 n4297m.
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.
“Great seller and nice family! The pin was in great shape and as described.”
“Purchased a machine that he had listed on another site, well described and excellent condition. Great Pinsider!”
