I'm having coupon code on sidebar on my product categories list, cart and checkout page. Whenever I'm trying to add coupon code while being on the product or category list page or checkout page, it is taking me to the cart page. Is there any way I can make it apply on the same page without redirecting or reloading with the help of ajax?
