$66 for an 8 -12 inch tree? OMG I wonder why it is grafted and what is the root stock. Likely one of the reasons it is so expensive. Plus he is paying the patent holder fee.
Ouch. Even if you could find seeds, it is highly doubtful they would be true.
Did they suggest you winter this over indoors?
From the offer, I find this a bit troublesome:
"This is the time to buy to ship. Best time to ship and plant."
Depending on WHERE this is to be shipped, this is BS.
