I can't buy my nic from OneStopDiyShop for reasons they don't control.
But they are on my A+ list of vendors I love. Awesome people with service even more amazing.
Strongly agreeing with the sentiment of buying 100% bases where bases are the predominant mixture of PG or VG. If you like 80% PG in the juice you vape, buy 100% PG nic. If you like 80% VG, buy 100% VG nic.
