What causes perfume/Soap taste? I got it once from a rose so I don't buy floral, but today from a necterine flavor, was given to me from an x vaporer so I don't know how old it is. Any way to tell before I fill my tank, cuz they both smell great. Any Vetran Vapors here that can suggest an online store with awesome flavors and prices that this kind of thing doesn't happen? Apparently my favorites don't sell online, :-(
