Hey man, you can give VT here a shot they got some pretty rad juices. I would recommend trying Dulcis or Mentha
Also tastyvapor has a great deal on liquid. You can buy 1 30ml bottle of 48mg nic for $15.00 and a 60ml doubler ( liquid without nic ) for $10.00 and mix them all to get 90ml of16mg E-liquid all for $25.00
just keep in mind it will take a little bit longer for you to recieve your order from them as they mix there own E-liquid to order.
For you second question of VG vs PG
PG = more throat hit
VG = more vapor
I found that mixing them togethor is the best way to vape. evan a 90/10 of PG/VG is very noticable.
