I think they will ship, and you get a couple of bucks off if you buy a whole pallet, but I'm not in that league now nor will I ever be!
I don't use Sungro - is that similar?
I like the Sunshine Xix #4 because it has larger sized perlite and pumice, so doesn't break down as quickly. You could use any kind of mix and add more perlite for the same effect, but now I've been using this mix for about six years and I've figured out the watering schedule and all the other factors.
The downsize of course is that it's peat based, so it's not considered sustainable. I'm not sure what I'll do when they clean out all the peat...
