Az state parks... UPS delivery?

I would not chance it, and see if it could be delivered to the local UPS Store, or distribution center. Perhaps if you get to know a business owner, they might accept the items for you, as long as you are not ordering things from NAPA online and delivering them to your friendly auto parts store, they might not like you ordering from their competition!

I don't know how far your place is from a large town. If more than a 30 mile drive to a UPS store, it might not be worth it. .

Good luck,

Fred.
