how do you sell to a medical shop?

how do you sell home grow indoor to a medical shop? like if your a legal patient would it be legal for you to sell to other patients or shops?

I talked to a couple of shops where I live, let them know I was growing/ wholesaling and they said when I harvest, bring at least 1 gram by for them to sample. Then negotiate a fair price. You just have to remember, most shops will want to buy it fairly cheap, so they can have margin.
