Then there's a LOT of people that have stuff up for sale against TOS...there's Cotton Bacon specifically for vaping (description even talks about e-liquids), Aspire Nautilus and lots of other tanks, coil replacements, mods, etc. You can buy a whole set up off Amazon.

When I was stuffing my own cigs, I bought my stuffing machine and filtered tubes from Amazon Prime, just not the tobacco. That's why I never thought that anything other then the liquids/tobacco (i.e. the stuff with the actual nicotine) were against ToS.
