What we did was instead of using special offers module, we created a normal product category called "Specials" (or whatever) and used this third-party module:
http://www.websitecm.com/x-cart-mods/multiple-product-listing-templates-for-xcart.html
It allows you to assign a different style of template to each category/subcategory.
So we modified the existing product listing template to display only particular data (such as the market price) and assigned it to that category only...
Useful mod - I think XC should include this facility is future versions
