Good list, I noticed redat from eBay US is in their. He sells a lot of parts but he charges "handling" fees nit just postage. I haven't checked recently but when i bought stuff a few years ago the part cost $3 to post and he charged me $30 US. And that was when the dollar was at about 0.60 not like it is today.
He may have changed his practices but i think if you are charging a "handling" fee on eBay it should be clearly stated.
