You're right @Eodine, that's the big difference "the technology". With technology, everything is done through a computer or phone, contrary to the offline business where everything is done physically. Many prefer online stores which is currently booming.I think the big difference between offline and online business is the method of application of the use of technology. In online businesses, we make use of the online means of communication to start and finalize transactions while physical is eye to eye contact.
