How can I create the list of discount products?

Hi all,
I use the cosmetics template. But now, I dont know the way to create the discount products? Can you help me???

You have that in product options (per each product), also you have discounts based on customer account group and coupons, best if you go thou some VM manual.

I want to display only the discount products, but the VM list all products now. How can I filter and display??

There is no such filter in VM
