Some of the TPGs will also charge more depending on value of card, so cards like the Mays/Robinson/Mantle will likely cost more than others.

The great thing with most of the Auction houses is they will offer to deduct the grading cost off the final number that you get as a return for the sale.
So they'll carry the outlay for you until the cards have sold and simply hold back the grading fees as well as any other negotiated fees or premium.

Thanks for that info.
