All good ideas. I will look into each link/idea. Seems like all the places I've shopped only carry 18g blunt needles now. So does not work with the genuine 510 cartos. Even the Boge's and similar work better with a sharp needle though.
I just called Walgreens and they said you need a prescription for anything bigger than 29g (gauge sizes are reversed so 20g is much bigger.) Said it was the law. So not sure how people are getting them from Walmart. (I am in Washington.)
BTW the owner of Crystalclearvaping.com will send some good ones if you call him. Don't know why he doesn't list them though. He is a great guy to do business with.
However, I am here looking for a place where I don't have to pay extra shipping to order my Joye cartos and needles together. Someone here said they were super cheap at the pharmacy as well, like .30 cents, so was hoping not to pay $2.00 each. Will post back if I find something better than what's listed above.
