Not advocating it but if you choose to receive funds via any of the popular services for any reason: After receiving, transfer out and wait until the funds actually clear into your real bank account before goods are exchanged, there's no way that I am aware of to get scammed if you do it that way. That's what I do. Add a waiting period.
