@Anthonyvaper @JohnNada is pretty much correct. We stopped allowing the sale, swapping of Liquids that were "Shortfills" that had Nic Shots added as there were some concerns raised about the qualities of those shots at the time. TPD did cause a lot of problems in that some users mixed to higher Nic levels than "technically" was allowed after the implementation of TPD so we stopped allowing the sale or exchanging as POTV could not be seen to fly in the face of the rules. Also, we couldn't be held responsible if the Nic used was of a questionable quality.
We DO allow sales and exchanges, but
ONLY if there is NO Nic added to the liquid.
