Aroma Ejuice (WTA) is based in or near AZ as best as I can recall. I know my WTA arrived with speed. If looking for online vendors, I've also used CA vendors from time to time (please don't ask me who, I just can't remember) but stuff tends to arrive fast from that area.
I am pretty "low' on suggestions for in person vape stores, but I don't frequent them much anymore. Pretty much any USA vendor is going to give you decent speed as far as delivery for the most part. I tend to look at pricing more than location, necessarily and I'll use Chinese vendors on occasion, especially for things I don't need/want right away.
You could google search some stores near you and post them for opinions from those who've used them, I'd guess. There are just so many vendors to keep track of. Best of luck in your search!
