Did you get the VG in store or online at WM?
In store. It's near the rubbing alcohol I believe. Just make sure it says "USP". It's the full name too not just "VG". If it's not near the rubbing alcohol, it should be near the bandages or in that general area. I think I paid 3-5 bucks and it was between 90-120ml.
There was some discussion about it on the forum in the past. People have been using it for awhile and I personally have no reason to believe it's not 100% safe. It's USP Grade and the manufacture has stated maybe .05% water...or something like that. I've vaped it straight before just to see if it had a sweet taste....it's perfectly fine in my opinion. I'm not a chemist or anything to make significant claims so I'm throwing up a disclaimer...at your own discretion, for this post
Search walmart VG and you should find some post though. I hardly ever use it unless I get a really strong liquid I added flavor shots too.
Either I store it away in case of really hard times or I PIF to someone who is in dire need.
