I'd talk to the plant inspection folks local to you and make sure they're happy with how you're filling the form out. Mine here basically said fill it out and mail it in, but I got a cranky call from some lady up in Gainesville because those guys were supposed to come out and inspect before I sent it in I guess. At least that's what she seemed to think. Maybe I wasn't supposed to check the nurseryman vs stock dealer boxes? Either way, one of the local inspectors showed up here out of the blue a few months later and I'm good to go now. Call them, they're there to answer all of our stupid questions about their stupid forms. ;-)
I've had no problem getting wholesale pricing with just my certificate of nursery registration, but apparently that may vary place to place.
What these other folks are saying about a resale certificate for supplies and other taxable things you may sell is absolutely correct. I'm just begging to differ on the necessity for strictly fruit tree and other food producing plant/seed/cutting sales, since they're exempt from sales tax in FL. If a nursery is charging you sales tax on fruit trees even without a resale cert, they're doing it wrong.

I think you are correct as that is the form and the people I had called today. Where I was confused is where I think you need an inspection for one of the choices. I would be option 2 (stock dealer) since I would be buying and selling and not growing and selling. I also probably need a resale cert to buy from the nurseries as well to keep from paying their sales tax. This might be all I need to get this done. Thank you!
