Too much, but less than I did on stinkies. My wife and I started vaping to get off the analogs and we have been successful doing so. This is the big benefit for us. I think in the long term we will end up saving a bit, since we have invested in rebuildables, but we buy a lot of juices to try them, enjoy getting some new toys (some nice rebuildable drippers, most recently) and don't think much about it. We did this to stop smoking, not necessarily to save money. If we do save a few bucks in the long term, great. But not the point.
