I was lucky enough to go to the vaperite brick and mortar store to start, they had a juice bar and a friendly staff, and I got to try some things before I bought them. If you can make it to Indianapolis, they have a vape shop listed on the directory, perhaps with a juice bar.
Barring that, a sample pack is a good idea, especially if you don't know what you like in juice yet (candy, fruit, tobacco, bakery, drinks etc) I have gotten some things from other places and had mixed results (not their fault, just stuff I thought I wanted to vape, and then, not so much...)
Alice in Vapeland is my own personal favorite vendor, and they have a sample pack.
