Hobby Lobby also carries a few Lorann flavors.
You cannot use most of the flavors sold in grocery stores, because they're for cooking/baking, and contain ingredients that would either be very bad to inhale, or would gunk up coils something awful. For
vaping, you need pure flavors, which are in PG and/or alcohol, and there are a few that are in VG, for those with PG sensitivity.
Splenda is an excellent example -- it's sucralose, which is fine for
vaping, but it also contains maltodextrin, which is BAD!!! for vaping; it's actually a form of sugar, which would turn your coils into a stinking black mess in nothing-flat.
Most vape shops won't carry flavors, because they'd rather sell you 300%-markup ejuice. So ordering online is really the only option, unless you can pick up from the TFA warehouse as mentioned above, or you're content with the very few Lorann flavors available in stores -- and not all the Lorann flavors are suitable for vaping, since they're really for candy-making.
