It is up to you to have some idea of postage costs. By buying you saw the postage cost quoted and agreed to it.
You should have compared prices before buying. It is not just postage, buying a Camera at £20 with £20 postage is exactly the same as buying a Camera at £30 with £10 postage. It is what you receive for the total cost that matters.
