In the retail sector.......
This will apply to some industries.... but not all of them by any means.
Retailers often buy products from wholesalers/distributors, instead of going direct to the manufacturer. They get better pricing and better service this way.
But.... manufacturers often have an "authorized dealer" section on their sites.
Find those that do, apply for an account to buy direct, and become an authorized dealer, requesting that your info be added to that section of their site.
Even if you never make a direct purchase, you're now an "authorized dealer" with another good link.
