How about if you star buying sample boxes, like they send you 5 or 6 e-juices monthly, I can remember having the same problem, I live in Tijuana and cant buy my .... other than mail orders or the 2 local vape shops, the really good thing is that one of the shops give you flavor testing before you actually buy something, I had this experience were I taste one good flavor but in my vape it taste horrible, so Im guessing here, maybe is your Vape equipment and not the flavors, also in my experience I find some flavor that I didn't like at first really tasty with alcohol, coffee or different drinks, Arizona works wonders with some flavor, like watermelon. Hope you will find you perfect e-juice cheers from Tijuana.
