Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
