For retail sales of the stuff I keep there, they charge 30% and I have no problem with that - I chalk it up as marketing. My prices at the store are the same as my regular prices, not wanting to compete with myself.

The problem is;
When a customer takes a liking to something but wants to have it customized, they ask the store manager if I do custom work. The manager directs them to the stack of business cards and tells them to contact me directly. But then expects me to pay them 30% as though they sold a piece from the display. I have a problem with that.
Am I wrong?
