The Candy King line are pretty good if you like candy. There's thousands of different flavors, and I suggest you go visit a local vape shop and try different ones to see which you like. Once you've figured out ones you like, look for them online as they're WAY cheaper than in any vape shop. You can then also start browsing the hundreds of online stores that are similar flavors to the ones you like and go from there.
There's also various vape juice subscription services you can try signing up for that will send you new random juices every month based on flavors you like. You can look into those as well. Personally I like vape-box.com. Though they can be cheaper than going into a B&M store, they're still often more expensive than buying it direct from an online vendor. But it's nice to get a variety, and if you've got extra money to spend, it could be fun.
