Looking for a social discount module but acting on the product no a FB page

[JuanLaSambuca]

Hi guys,

 

I saw free interesting modulos offering social discount but they act on the FB page. I would like this but acting on the product so what it's shared in the product and no a like into the general FB page. Any idea?

 

Im looking something more like http://demo-shoes-lovers.social-buy.com/catalog/category/view/id/10/

 

I would like to give discount to users who like the product first (no my FB page).

 

Thanks in advance
