Do you have an out of state friend who could order for you then send it on? I highly doubt a homemade package from a friend would be stopped by customs if they just repackaged it? Is there even such a thing as out of state customs on a homemade.... well, it's nic, so that probably means you'd need to ship it ground, and labeled as hazmat... NVM.
I realize the upfront costs can be a bit daunting, but aren't you being charged that tax for premade juices when you buy online? I really think this might be a time to just buy stronger nic, like 100mg/ml (since they tax per ml, not per strength) and go for it, if there's any way possible. Any family out of state going to be sending you gifts this Christmas and etc.? Travel?
I would also consider a greyhound bus trip, and I hate the bus. With that said, I'm pretty passionate about DIY and the cost savings. I LOVE that I've paid for almost everything I need for the next while already.... It is a huge savings over time.
Or, just buy a really small bottle of nic to test out DIY and see how you like it (it can be a bit intimidating up front but it's really fun once you get going with it....)
Or, you know, just continue doing what you are doing, but I can pretty much guarantee that e-liquid (of all sorts) is only going to get more expensive/harder to get, as you are seeing in your backwards state. Just imagine once the Feds jump in.
Sell blood plasma? (I'm not kidding, I might do it in your circumstance, if I were physically able to do so). I think I can, I've never had the need, which I am so thoroughly grateful for, but I don't rule out these types of things, really....
