I am so scared because I do not know anything about building mods or making eliquid....i just buy my parts on ebay and go about my business.
First of all, Now is Not the time to Panic or to be Scarred. Because there is some Time Left.
But Now is the Time to start Making some Plans.
You say you use Drop In Coils. That's Cool. But they probably Won't be readily available in 6 Months or so. So Now would be a Good Time to think about getting an Rebuildable RTA and doing some Coil Building practice.
Same with doing DIY. It Isn't hard. If you can Mix a Rum n' Coke, you can do DIY. It just takes a little Practice. Now would be a Good Time to Buy Some Nicotine Base and a handful of Flavors.
If you Started Now, even if ALL the Flavors are pulled in 60 Days, and your Main e-Liquid supplier goes Belly Up, you should have by then 3 or 4 very Vapable Recipes. So you would be Self Sufficient.
Like I said, the Sky Isn't Falling Today. You still have some Time.
And think of it like Getting Ready to go on a Big Camping Trip. You wouldn't wait till the Last Minute to get things Ready. You'd make a List of the Things you Need. And then Check them off as you get them.
