MarketPress Lite mod: how to move the 'buynow'/'addtocart' button

pretty simple really, i use MarketPress Lite on my site, here’s an example of how it looks on a product page now, i’d like the buy buttons to be at the top of the page as well as, or instead of the bottom of them.

Can’t find the style sheets code or anything related to this, how does one make that kind of simple change? Again i want the button to just move to the top of the page/post is all. help?

thanks!
