E-commerce Offering Mobile App

There are various websites in the market for doing business that offer many types of offers and their case studies are very high level. In my lowest thinking, I think that on an offer website where people can only see the offer but not buy it, they have to visit the specific website to buy the product for which the offer is offered, which is a bad experience. For that, I have made a small UI through which a user can easily buy the products he offers which is a good experience.
