Welcome Patty:
If I were you, I might consider checking out some of the vape vendors who sell small 10 mg bottles of flavor, as a group, so you can try a bunch of things, and ask them to include cherries and grape.
The only vendor I know of in the US that will offer free samples is Freedom Smoke USA, if you have one near you you may wish to check them out. I'm fond of this place for
juice, though it's hardly the best
juice out there, it's sort of middle of the road. Some of the other vape shops will charge, like 50c per sample, so you can certainly try other juices, it just won't be free.
Good luck! Personally, the idea of either of those flavors is not to my taste, but you should have no problem finding what you need, over time.
Good luck!
Anna
