I guess Ecig Ave. I bought a tank there for $21.99 shipped with free shipping using StarreDeal as a discount code. Sadly, they do not have additional coils in stock. Hence this post..The place I normally go to has a great deal on the tank itself but the heads are out of stock. I just picked one up - excited to try it.
I'm looking for the cheapest and best source for coils, specifically for the Starre, but please share info for any subtank.
