I Dont bid on HA or BH, for whatever reason, doesn't matter. But complaining about buyers premiums, well, its al there, happens on auctions all over the world, dont like it? protest with your wallet and don't use it. Some people wont buy off dealers direct as they think its too expensive, they prefer getting bargains off ebay, thats their choice, some people dont use ebay, as they are not certain of what they will get, some people don't trust auction houses, some don't trust certain dealers. Its a choice. This isnt air or water, we dont need it. Buy it if you want.
On a slight tangent, but sort of related, many will know I sell Gold (and Rare Coins and Banknotes) for a living, people come in DAILY and ask for the price of gold, as in what we sell for, theres always a % over the spot/market price they see on TV, and they complain.
It makes me grey, how often I have to explain, WE ARE NOT A CHARITY, WE NEED TO MAKE MONEY (I put it nicely). Sometimes people walk out. They expect to be able to buy and sell for the same price. Regardless of wages, rent, power, taxes, etc etc etc we need to pay, PLUS its a business, need to make a profit.
So I guess in my rambling I am saying, HA (again I dont bid or sell through - no desire) are there to make a buck, if they charge both buyer and seller, and both know (or are to lazy to read the fine print) thats fine, if they bid on their own auctions, while I dont like the idea, if its legal (I dont know) and is disclosed, ditto.
I am sure Ive said it before, I dont like MacDonalds, thats why I dont eat there.
