Yeah, you definitely save money with rebuildables. I was at a brick and mortar the other day and was told rebuildables are now illegal to sell here. Something to do with child safety. I don't buy it. Big tobacco losing too much money.It was joked on a few videos I watched today that the return to build mods and tanks may be coming.
I have never done so, but one might want to stock up on mods and rda's RTA's over the next few months. Nicotine is also becoming harder to acquire, and (I believe imo) that it will become more expensive.
Luckily I have a few rtas, rdtas and an RDA. But I think they will still be available online. You always want the next one once you start buying them.
