First off - using ego or mouth to lung whatever you may want to call it and the average 30ml for a tenner of high PG stuff I believe it certainly is possible to save a huge wedge but for us subohmers especially those that rebuild or use tanks like the tfv8 etc I believe no unless you mix your own juice. To be fair I'm not fussed about the extra I spend compared to smoking as I love rebuilding and trying all manner of different juices both shop bought and home brew.... To many as said before in the thread it's more of a hobby, an expensive one at that haha specially with how fast the industry has moved and the amount of products and juices coming out on a daily basis.
