One of the advantages of ecommerce is that customers can see the momentary total of their shopping cart during the purchasing process. This benefit, however, may be a disadvantage for the e-merchant, since the final sum may be less than the one the shopper would spend in a brick-and-mortar store. Therefore the online sellers often use loyalty rewards or volume discounts, which can be managed within the Magento discount system.
Being an online shop operator, one of your primary tasks is retaining your customers. Instead of continuously looking for new ones, you have to pay attention to keeping the old ones satisfied and also to reactivating them.
