I want everything to be easy, smooth and fast for customers. I have a feeling that the more complicated the buying and ordering process is, the less likely I am to retain customers.
It can really work like that, and I believe that any business owner should think about optimizing the shopping and checkout process among other things. Various extensions like magento 2 add order attribute programmatically can really make this process more optimized and convenient for the shopper. Including he won't have to enter his details next time.
