Add discount for out of stock products when adding to cart

[abdullacm]

Hi all,

 

I want to add 10% discount to all out of stock products when the item is added to cart. For example a product A is out of stock and is having 20% of discount from some other specific prices, when the user add the item to cart additional of 10% discount to be added to the price.

How can i do it, i have tried to modify the pricecalculation method of Product class, but modifying that affects the entire site where the price is shown. I want the additional discount price only when adding to cart and in cart items.

 

 

Thanks,
