Jim,
I got a chance to go to Make-A-Cake. Thanks for the info, they are right around the corner from Amazing that I mentioned. Their selection is a little better but they didn't have the droppers. Their glycerine, branded CK Products, wasn't labeled are vegetable or USP. Is this what you have used? I was hesitant to buy a liter of it.
I am liking the fruit flavors as a nice change of pace from the tobaccos and I have a new favorite. Banana Creme is great. Its like a banana flavored runt candy. May not sound like something everyone would want to be "smoking" or "vaping" but I really like it.
