First,
P&P refunds trade tokens for canceled trades when certain criteria are met. The criteria for a token being "spent" is available on the "Buy Trade Tokens" page in the FAQ section (
Buy Trade Tokens | Pin & Pop). I believe the refund happens once the declined pin is mailed to you.
Second,
it is possible to provide access to images of your pins during trade arcades. I use imgur.com to upload pictures of flawed pins, then I add the URLs to the condition notes for the respective pins. All of this prep work doesn't matter if the other party does not read the condition notes, but at least I did my part. Also, providing this information can help ensure a trade token refund if the other party cancels the trade.
Lastly,
P&P is taking a lot of heat for the behavior of trade arcade participants. P&P provides magnified photos of the pins, but it is the party on the other side of the trade who makes the decision to cancel the trade. When a trade is canceled for questionable reasons, I am more concerned with identifying that trader than canceling my P&P VIP membership.
I don't live near any Disney parks or stores, and I find individual mail trading exhausting due to the constant back and forth. Therefore, trade arcades are my favorite way to trade. I receive dozens of authenticated pins every 4-6 weeks, so I think the cost of postage and tokens is fair. I was hesitant to participate in the second chance boards at first, but I have decided to list my rejected pins since they are already at P&P. I lose nothing if there is no interest in my pins, but at least I won't miss possible trade opportunities.
Good luck to everyone participating in the next trade arcade. 😊
