vape meet might be great for testing if you can go to one. There's also the classifieds, you'd lose some money, but you could try to sell or trade bottles you don't like, most people do seem to like Halo, so it should be an easy sell. Did ya check *the* list .. you didn't check the list.

I'll pm you one other site that *might* have it. It's one of those ones you need to make an account and I don't particularly want to make an account to double check though, sorry.
If you haven't I'd also consider emailing jugheads, he might have some samples that he just doesn't have listed.
Edit: You'd need to do the verification for the classifieds though.
