Hello and welcome
I too made the mistake of ordering blind when I first started, luckily there wasn't much that I couldn't stand, just a lot of stuff I didn't particularly enjoy.
So I would suggest trying before you buy, or like others have said buy the smaller 10ml bottles.
I don't really use them anymore but LiQuid might be worth trying if you're interested in experimenting with new flavours.
For me I'm pretty much an exclusive Prime Vapes addict and will happily buy blind from them!
