Stores have humongous overhead. They have to pay rent, and have full-time employees manning it. An amazon store, can have a warehouse in the middle of nowhere, (where rent is cheap), and employee wages are lower. Also be aware that items like e.g. cameras, there is barely any mark up at all, and many stores make their profit solely on accessories, etc.
Now, I do feel good going to a store, and supporting the local business owners. However, it’s upsetting to spend so much time waiting to be attended to, (as they are attending to other customers), and then finding out that the size of the shoes I want is not in stock. So, I do prefer
as a convenience to buy everything online.
