I'm trying to set up a pricing table (like you have, comparing the 3 different options, and the buy option is not the regular little white buy now button) and am wondering how to do that. I have a table set up with my theme, and a "buy now" button, but I'm not able to insert the [mp_buy_button_product_id="109"context="single"] shortcode into it to get the button to add the product to the shopping cart in Marketpress. Is there a way to do that?

Thanks!
