Ive been caught out before also but as it states P&H (postage and HANDLING) .. handling can be the person's process in getting the item to you.. in such, ebay fees, internet fees, paypal fees or even employee fees if they are employing someone to "handle" your transaction.

Unfortunaly you maybe stuck with it this time, it is a very sly way for them to do it though. Just make sure you mension something in the feedback you leave so that others in the future may not get caught out too.
