If you are low on funds, get rid of the carts and order a Vivi Nova for $12.95 from Madvapes. They also have Dekang juice for $10.99 in the 50ml size. At 4ml a day 50ml lasts me almost 3 weeks. Dekang tobacco and RY4 are good vapes for the money, IMO. You will probably find that they match the tobacco flavors you get in the typical prefilled cartridge.
Eh, it would work. But, I wouldn't want to get caught dead carrying one of those. There's a lot of druggies in my town and the last thing I need is to be accused of being one of them. I much prefer something that resembles a traditional cigarette more. At least, for now. Later on I might start looking into more advanced stuff for use at home.
