I've had the same issues as you with juice prices honestly. Some of the best, most amazing juices out there, are charging $15-$30 for 30ml and I just can't afford that. I'd be spending more on juice than I ever was on cigarettes because I vape A LOT.
I've recently come up with a solution for myself so I can enjoy awesome expensive juice as a treat and regular old bulk juice as my all day vape.
For my all day vape setup, I'm using standard dual coil carto tanks. The dual coil cartos are cheap to replace and I use massive amounts of "clearish" vaping liquid (little to no sweetener, non-dark colors so they don't gunk up so quickly). I've been buying the big 4oz bottles of juice from TastyVapor and have been mixing them with some bulk flavorless nic juice. About a week ago, I found BlueMistVaping selling pre-mixed flavored liquids at 180ml for $30 and have been enjoying them as an all day vape.
For my "this is a treat" juice setup, my next planned purchases are going to be some high quality atomizers. I haven't easily found any Ciscos so that makes the choice of Ikenvape atomizers pretty easy for me. With those, I'm allowing myself to get some of the "best of the best" juice out there, probably a sample pack of Pink Spot which everyone seems to recommend to me. To switch between flavors, I'll probably pick up some flavorless PG in bulk from BMV to vape out between juices. Hopefully it won't take me long to find something I really love as my treat. Once I do, I plan to just keep the Ikenvape atomizers and high quality juice stuff at home for when I get back from work or whatever I'm doing during the day.
Idk if that sounds like an idea you might like, but that's my plan
