So I'm looking at recipes for my first DIY and I figure I'll start easy before trying the more detailed mixes. I'll probably start with something like Kosher 99.x% VG mixed with 100mg PG to bring it down to 20mg and then Red Bull PG flavoring or maybe a mango to bring it down to about 17-18mg and about 75/25 VG/PG. Let me just say prices and descriptions are all over the board so I haven't figured out a good way to judge what I'm getting. Some places say one drop of their CONCENTRATE in a 10ml solution is more than enough and others suggest that their FLAVORING needs to be 20% of the final solution. So are there two or more different types of flavoring out there. So for instance is there a Mango concentrate and different mangos that are already mixed with varying amounts PG? And hopefully I'm not being too blunt, BUT a lot of the websites I look at are trying to sale things, like VG, that is two to four times the price of most local "retail" stores. I'm guessing that the flavorings are the same way. I understand that they need to make their money too, but it just seems like ALOT of the sites aren't priced correctly. You look at one site for 100mg base and it's $20 for 120ml and then the next site has it for $60. .... Anyway's, I'll stop before I get off on a rant.
