You can use this FREE extension called "Discount Limiter" which helps to set the maximum discount amount (upper limit) for a percentage-based cart rule:
Hello there, buddy. What a brilliant concept. If I knew how, I'd be delighted to assist you. I am a thrifty shopper who frequently purchases products from online stores. As a result, I frequently visit sites such as https://www.dontpayfull.com, where you can discover a variety of discount coupons, but I've never seen such a brilliant idea in any online store. I'd like to request that you notify me when you launch your online store and actualize your wonderful vision.
It is a very competent approach. I wish I could help in some way, but the only thing I know is that most extensions only allow you to achieve the required functionality for groups of customers, but not for an individual customer. So think about how much you need this service. Evaluate the cost and capabilities. Before buying, I always try to research the product price, possible discounts and promotions. Hey Discount is my latest discovery. I really need to save money right now, and it would be great to find discounts on things I need to buy. You can find a lot of discount coupons there. If you run your online store, let me know. I'll be happy for you and I'll be sure to come to check it out.
