Need to get Promotions (Gifts) for relevant product item

Hi All,

I have requirement to dispaly a message in cart if gift item quantity is 0 for relevant promotion item. We are using Epi Promoengine  to calculate gift promotions and if gift item quantity is 0, promoengine will remove it from the cart.

So in this case we dont know what is the relevant gift item attached to selected promo product item, hence we cant decide to show the message (eg: You cant have the gift item due to the insufficient stock)

We would like to know is tehre a way to get applied promotions for a particular product item, if so how are could we do that?

Please help me to solve this issue?

Thank you.
