Moon mountain vapor is pretty cheap, and I've been really impressed with them. The cheapest liquid I use in my daily rotation. 10-full 10mL(~12mL) bottles for about $45. I haven't found anything, outside the five vendors already used before daily, that I would use..enjoy. I'm glad I stumbled into them.

got these http://www.steamjuice.us/ deal of the day is the rounder 3 bottles 120 mil of your choice of flavors. Having sampled Thick Vanilla Custard, Green Fairy Absinthe and Cheesecake Your Way Strawberry I placed the order 59.99 for 360 ml is hard to beat....just under 17 cents per ML
vaping right this second!! MBV 'Pumpkin Spice' flavoring mixed at 5% was a bit 'sharp' for me so I added 5% 'Cheesecake' and I'm really enjoying it.
MBV's flavorings are $2.99 for 15mL. As an example, to make 30mL of my pumpkin spice cheesecake, I'd mix 27mL of base, 1.5mL cheesecake and 1.5mL pumpkin spice. That's about 60 cents worth of flavoring and the cost of your base unflavored nicotine liquid (which can vary wildly depending on where and how much you get).
