I don't do swaps but I ship a lot and do most of it online through Paypal. It is well worth it to get a PP account if you ship a lot of things, you save on postage and get Delivery Confirmation free or at a reduced rate.

And PLEASE be an informed consumer. Don't wander into the PO with an item to ship and throw yourself on the mercy of the clerk - they are trained to "upsell" - get you to buy the higher priced postage when you don't need it. Know how much it will cost and what service you want before you get there. It isn't that hard (although the consumer confusion dept of the PO works overtime to make it that way).
