I've used importnicotine, which is anything but cheap shipping at $65, but took only a few days. and I've used myfreedomsmokes, which took 4 weeks and cost $40 to ship.
always search for a coupon code where ever you
buy it from, that goes for anything bought on the internet. I got $10 off my order with mfs with a coupon.
also, mfs sells beakers, syringes, empty bottles and everything else you need to safely mix nicotine
juice, as well as flavours.
