I am in Gilbert, which is east of Phoenix (contrary to popular belief, the cities surrounding Phoenix are cities and not suburbs!). I think it would probably be about a couple bucks to ship out a bottle, they're only 4 ounces. I'll let you know for sure tomorrow, I'm shipping some out.
Let me just tell you, I have always used this stuff and it's worth every penny, even when I was paying almost 12 bucks for a 4 ouncer! I have brought
plants with 1/2 of a leaf back to life with it. I usually put a capful into a 2-gallon can and use it like that, and in AZ I water a lot and I still only use about a bottle a month. (I'd probably be better off going on the website and buying a bulk bottle for the long run, but that's a lot of cash up front!)
