Business Design & Development works with business owners who want to design and develop a profitable presence on the internet.  For all of this to be possible, you need to create a domain.

Can you establish a retail presence in  an auction store?  Yes!  Does that require a domain? No! 

Business Design & Development works business owners who want to establish a profitable stand alone internet retail business. 

A domain is a name for the business on the internet.  For example:  expeim.com

Business owners can check the availability of domain names at www.expeimdomains.com .  If available, domains need to be paid for.  When you pay for the domain, it becomes registered for the time period you specified and paid for (minimum - 1 year and a maximum - 10 years).  If you pay for just one year, the registration expires at the end of that year.  Business owners should monitor and renew the registration at appropriate time intervals, in order to maintain ownership of that domain.
