A PWE is a shipping method sometimes used for mailing trading cards. PWE stands for Plain White Envelope. When a trading card is shipped this way, the seller mails the item in a regular flat envelope with a postage stamp and no tracking for the shipment is provided. This shipping method is most commonly used in peer to peer transactions and it is often implied that in return for a significantly reduced shipping cost (free or the cost of the stamp) the buyer will assume the risk if the shipment is lost in the mail. For that reason, PWE Shipping should only be requested or accepted in situations where the seller has a track record of positive feedback and the buyer trusts that the card will be shipped.
