Just getting into DIY and I'm looking to buy 100 MG VG base. I'll only be mixing 3 to 6 MG juice and I'm wondering is there any difference between the high cost Nic from nude versus the Nic I'm seeing everywhere for 45 to 50 bucks a liter? I have had harsh eliquid from vendors at 6 MG and I've always thought it must be cheaper Nic but not sure if I was just a noob. So my main question I guess is spending the extra money worth it?
