As stated earlier, you'll have to start a juice rotation of sorts where you are vaping a set of juice while your next set is steeping. It's tough in the beginning, but once you find your favs or daily vapes, then you can just order large bottles. Also some juice vendors can take up to 2 weeks to ship something out, then you add in your steep times, and it'll be a month from the time you order before you find certain flavors to be good enough to vape which is something to keep in mind. Of course you can drip some juice as they are steeping to see if they are ready or good enough for your palette.
When I first started, I bought juice from Vaper Venue called Monkey Cream and Monkey Buns that was great for me since they shipped fast, and the juice was good as soon as I got it. Other juices that I found were good right out of the mail were AiV's Crunkberry and A Quiet Morning, AVE's Bobas Bounty (at least to me), and a couple fruity menthol/ice vapes from Mount Baker Vapor. However, I will say some of my fav juices are ones that I showed some patience with like HHV and Ahlusion.
