One of the many reasons, and probably the biggest one, to quit smoking was because of the money. Buying the juice from other websites in the 30ml sounded good, but now I've come across a few websites, (myfreedomsmokes.com, and the bear juice) which seem to have some really good prices for bulk, unflavored juice. It looks like I can save a ton of money by diluting myself, but what are the con's to this, if any? And, if i bought 250 or 500 mL of the 48mg bottle, is the only other thing i need flavor and pure PG? Is it difficult to get the mixture right?
