A web store is a real business no matter how you like to argue otherwise. That means since this is a real business you will need to put in real work into it. No get rich quick magic lies in an e-commerce store.
When you own a storefront you pay attention to displays and how your product is presented. You also pay attention to sales flyers, presentations and product descriptions. Sales associates will be well versed in what products are new and what products are well suited to accent virtually any purchase. In a clothing shop this means knowledge of what clothing choices work well together and what accessories will work well with a given ensemble. In a cosmetic shop it may be helping a customer find just the right shade of nailpolish or a scent that matches personality and taste.
