I can't understand all the complaining up here. Yes, PM takes a 20% commission and yes, the mandatory shipping is usually $5.95 per item, but that's all very clear when you sign up. I've bought and sold several items through PM with no problems that you wouldn't see selling elsewhere too (I'm an eBay seller as well). So if you don't like the commissions and shipping costs, don't use the service. If you order something and it's not shipped with the mandatory week, cancel the order and move on with your life. It's not the end of the world. Shipped something and the buyer claims you sent the wrong thing? Try to work it out through the dispute process and if you can't, again, move on. It's not like people are selling $10,000 cars up here. If these kind of things bother you that bad, maybe online selling isn't for you. Anyway, my PM experience has been good and I intend to keep using the service with the understanding that nothing is perfect, including the people who work for PM.
