I'm new to vaping so no expert but..
Purchase your salts separately and add your own to ejuice without nicotine.
I use a tobacco flavoured juice as a base and to that I add my own nicotine.

I use that as my base brew, which I fill my tanks about 3/4 fill then I top it up with the flavour of the month I'm trying... currently Pasha Momma's Fuji Apple.
No where that sells juice is reliable! unlike cigarettes your not on a flavour brand for life, but take what's available.
