For your best success when transplanting new trees and shrubs, it helps to have a specimen that was grown in your area, so it is already used to your climate conditions, rather than buying something that was trucked in from another state. Here's where Sander's has an advantage. They have fields where they grow their own stock.
I don't think they grow all the product they sell, so check with the salesman to verify where what you're buying was raised.
Located south of highway 412.
There is also a another large location in Broken Arrow.
