feedback question

[ironhorsecollectibles]

Once an buyer receives an item does He have to wait a certain period of time before He can leave a negative feedback !  Also does He have to request a refund before He leaves negative feedback. I noticed some buyers leave negative feedback but still keep the item and do not request a refund.

Buyers have to wait seven days before they can leave Negative feedback for Powersellers, no waiting period for anyone else. There is no requirement that a buyer request a refund or a return before leaving feedback.
