make buy now button more visible

Marketpress with gridmarket theme

A buyer has to scroll down to hit find the buy now button on a product listing. How do I place the buy now button higher up on the page so that the call to action is clear. Eg... a Buy widget so that the button is in plain site and doesn't get lost on the page.
