Ok thank you IL look them up but one concern I have is if the flavor will be as good as some of the shops
I've used ED quite a bit and honestly, their PG & VG is excellent so you shouldn't get an off flavor from the two chemicals themselves. That being said, flavor in general will be up to what you mix and at what %.
Comparing between vendors, I don't notice a difference between Essential Depot, Wizard Labs or RTSVapes when it comes to PG/VG; I've ordered from each of them. I still have some from each vendor and the smell and taste are pretty much identical. Unlike flavoring, there's not a massive number of produces of PG & VG, so most of it is going to be bought in bulk, relabeled and sold to the consume (i.e. you and I). As long as it's USP Grade (and theirs is), you're good to go.
As for flavor, what companies are you ordering from? There's quite a few threads for each vendor that can help out with flavor mixing (i.e. X flavor @ Y %). There's also a spreadsheet floating around which may help you a bit. It doesn't seem to be updated as often anymore, but it does give a good general start.
