Why would e-commerce be suitable as a way to increase sales?

E-commerce would not always be suitable as a way to
increase sales for all sorts of businesses.  However, it may certainly be
suitable.

E-commerce is suitable for increasing sales as
long as a firm's product is suitable for selling to people who are too far away to
conveniently come to a physical store.  Therefore, e-commerce would not tend to be very
suitable as a way to increase grocery sales.  However, for nonperishable things,
e-commerce is very suitable.  It allows people to buy from a particular firm even if
they are too far away to want to come to the firm's actual place of
business.
