I gotta agree with considering possible shipping...
I have a packaging/mail box store near me, that
I just take what I need to ship, they box and package,
then ship either UPS or FedEx...
The extra charge for packaging is very minimal...
You just need to explain that the tree's soil should
be plastic wrapped, and the pot and trunk should
be secured to the bottom of the box...
Then they usually fill it in with the dreaded peanuts,
that have been known to blow around the yard if
not careful... but, they work...
