Changing Marketpress "buy now" button

Hi there,
I'm wondering what is the best way to make changes to the Buy Now/Add to Cart button on Marketpress. I'm using it as more of a directory...rather than buy an item, the user is directed to the product's site. So I have "Product Listings Only" selected, and the Buy Now button directs to the outside url, so that all works fine. I just need to change the button to something like "More info." (in both the product list and the single product views)

I'm using Anubis theme.

Thanks!
