Good to hear from you again on Orchid. Companies can do that -- sell
only to people with resale licenses. You should get one. It's not
hard, you can get all the forms on line, and the annual paperwork
requirements are not onerous.
This is the jewelry industry -- people can refuse to sell to you for
lots of different reasons, like, they don't know you.
Nothing to get upset about, really, just find someone to order it
for you or get your own resale license. I think you're at a point
where you may as well go into business.
