eBay Feedback and DP users

[Emuaust]

I recently purchased some items off a seller from eBay, a seller that is a frequent user of these forums and I don't need to name names, they will know who they are when they see this thread.

My beef is the fact that when I got the parcel of goods I noticed he has charged three times the postage cost, $15 to ship 2 sms carts when the postage sticker shows $4.85. I usually don't complain when people charge a little extra, I have sold on eBay and better to be safe then sorry.

My question to users here is, what should I do, he refuses to talk to me and paypal don't care on postage costs, would you leave feedback on his DP thread if he advertised his auction in the "everything auctions" thread?

I don't want to appear an ass, but I would want to know if a seller gouges on postage before I bought from him.
