I can't wait to hear a follow-up. I live in Phoenix and have heard from acquaintances of ours that they go down there occasionally as well for their dental work. They are all very tiny people though and the mother of our acquaintance family says she can't be seen down there anymore because her mouth is too small for them to work on and she ends up in severe pain afterwards. Personally, I have also had someone give me amoxicillin from Mexico and I think it was a lot cheaper than $20, but that was also 3 years ago so hopefully prices haven't changed too much. Good luck and stay safe! I will Resteem your post even though my rep isn't too high seeing as I'm a new member on this site but I figure it wouldn't hurt either way to attempt to help another fellow Arizonan.
