Internal link to an existing listing

Hi,

I am using the coupon responsive theme.
I wrote a article in my blog and I want to link to an exiting coupon (listing) on my page. I made an internal link, but when you click on it, you only see the title, category and store of the coupon. I would like to see the complete coupon. When you look at the coupon on the homepage for example, you also see rating, description and the button to actually go to the store. Is this a setting I have to make somewhere?
