Displaying shipping price next to card price

I love the new market system, but there's one thing that is frustrating me.  When looking at the list of sellers selling a card, the listed prices can be very deceiving due to sellers charging different amounts for shipping.  If I'm going to be buying only one or two inexpensive cards, I want to see which seller offers the cheapest price PLUS shipping.  As a seller that offers free shipping, I want buys to be able to see that.
