One of the biggest advantages for doing business on the internet is the low or no cost that is involved in starting and managing the business.  Take the place where you do business which is the site, your online store.  Most sites can be setup for free by a hosting company.  You can either design it yourself or have someone design it for you, again for

free. 

Products for your business can be obtained for free from various affiliate programs.  You do not have to pay for storage of the product because this is done for you by the affiliate.  Once the prospect lands on the affiliate�s page they will sell, pack, and ship the merchandise for you.  Again, for free.  And you are paid a commission on the sale just for leading the prospect to the affiliate�s landing page through your promotions. ..
