Stubhub provides the mailing label for sending to the purchaser of the tix, and the purchaser isn't available when deluvery attempts are made, becuase the mailing required a signature. After 2 attempts, the putchaser doesn't follow up and the seller gets blamed & charged a penalty fee. Because it is the sellers responsibility to be sure the tix get delivered. Stubhub doesn't provide contact information for the purchaser so the seller can call & tell them to get your tix that are trying to be delivered. Then stubhub lies & states the called me & no call received-i can see who calls, I have all the proof of attempts to deliver & door tags left, but it is my fault the purchaser didn't get. Don't use them or you can be charged a fee, which is 100% of the sell if the tix.
