I would suggest you not start with a general flavoring kit as they are usually include staples you need for many recipes but rarely do they include enough to make a recipe that your are actually interested in. Look through ELR and find something you like…here is a simple one of 4 ingredients plus the VG/PG & Nic you will need that I happen to enjoy. http://e-liquid-recipes.com/recipe/220518/illuminati%20v2
I would suggest a vendor like Nicotine River for your supplies. Perhaps order your nicotine in the strength you like already premixed in either VG or PG (I went with vg). I like 70/30 so my first order included a gallon of VG and a liter of PG. What e-liquids do you normally vape now that you would like to be able to start making for yourself. The choices you have at your disposal are huge. Don’t find the volume anything but your guide… it is very simple to make your own vape and in the end, you will find that your are only spending $1-2 per bottle vs the $18-25 you might be paying at retail. Significant savings.
So with that $50 1st buy:
a dozen flavors you have found that will make 3 exact recipes you think sound ideal.
Also, check out www.onedropflavors.com and see if they still have any stock left from their introductory flavor line… 16 flavors for $0.79 each with free US shipping. $12.64 for all total. They only have 4,000 of each to sell and half were gone midday yesterday.
