Welcome Beetle, Guilty, and BoxOGoodies!
This has been a great source of support and information in the 8 months since I've quit smoking and have been vaping exclusively
Juices are pretty subjective. And, even if you find one that you like now, it may not be a favorite in a few weeks, months, etc. I was a menthol smoker, but I don't care much for tobacco flavors (even menthol tobacco). But, I may change my mind down the road. I'm big into fruits/vanillas/desserts/mints right now. I started DIYing my juice a few months ago, but when I was buying, I would stick to smaller bottles (unless I knew for sure it was an absolute winner) so I could try stuff and not get too burnt.
I've only bought juice from my local B&M, Mt. Baker Vapor, and Killer-Juice. Check Killer - they have weekend specials (Wed-Sun) that a few of their flavors are only about $3 for a 15mL bottle. When you order from Mt. Baker, they'll give you a free bottle with a minimum ($15 I think) order. Make sure you specify your nic, PG/VG, and flavor selection in the comments.
There are subscription plans (zamplebox and vape-box come to mind) where you pay a monthly fee, and they'll send you a number of bottles each month. I've never tried, but I've seen a few people mention it in other posts.
Good luck - let us know how you're getting along!
