Offering 'puja sale / discount'

I own an e-commerce business. Many of my competitors are offering 'puja sale.' In case you don't know, puja is a religious festival for Hindus. It's basically Eid for Hindus. Even though I'm not super religions, I do try my best to stay away from things that are Haram. Like everyone else I want to offer discounts too. But I'm not sure if it's permissible to do so. Please note that none of my products are specifically made for puja. I'm sure anyone who owns a business knows that discounts on festivals are great sales boosters and the products don't have to be related to the occasion itself.
