I'll add that the liquid is so worth it, it is so good. If you order the doubler to correspond to the regular w/nic bottles, it works out to cheaper than almost any other supplier. The doublers are the flavors with no nicotine so order 48mg of nic in the little bottle, a bottle of doubler in same flavor and cut it to your nic level. Very inexpensive this way. If you need more info, PM me.
