On my 3rd day so I'm not that far into it, but I spent $80 on the NPRO starter kit, then $8 on shipping for that. and then about $30 for the TrueVapor e-liquid. Will be buying more e-liquid very soon (within the next day or two most likely) and a new atomizer. The two batteries seem good so far, in 3 days I've only had to recharge one of the batteries and I'm getting near the end of the second battery. Trying to keep this cheap as I can, if it turns out to be as expensive as smoking analogs I will go back to them since I'm just doing this to save money.
