Hi Ace. Your best bet is to order some
e-liquid and refill (there are HEAPS of threads about this on this site). Much cheaper and you can get a variety of flavours.
I do not know any reputable Australian sellers, and order all my liquids and parts from overseas. If purchasing from China and being shipped via EMS you are looking at an average of 5 days to arrive.
You can also make your own
e-liquid. I use Glycerine and Queens food essences. Queens main ingredient is Propylene Glycol (which is used in most e-juices). None have killed any of my atomizers so far. These can be purchased for around a dollar at Woolworths! Chocolate is yummy, and if you add Coconut essence to the choc it tastes just like those Golden Rough chocolates!
