scrape card kingdom's buy offers for mtg cards

I'm not sure how viable this would be, but I can't imagine it would be technically challenging. 

It would be great if you could scrape Card Kingdom's buy offers for mtg cards. This would instantly give a very accurate read on the value of any card. Their numbers are updated fairly regularly too. I'd love to see what my list is cards is worth without having to enter them into card kingdoms website one by one.
