Ebay rip off and what is Pitney Bowes

[badgecollector]

I understand 10% goes to the gvt but shouldn't it be on the item only and not on the postage costs?
I paid $60us for a badge a week ago from the US and paid $34us in shipping fees
btw, the example I started this thread with I had actually asked what postage would be. the seller investigated and said 9gbp but when it cam time to ship he used that third party and I got slugged extra.
I have left negative feedback in the past regarding the rip off global and Pitney bowes but this has never appeared on the sellers feedback. ebay obviously vet the negative replies
