As many have said, try going to some local vapor shops because most if not all have samples you can try right there. Always try to support your local brick and mortar stores first then order on-line if you can't find the juice or vendor in your area.
I know you might find the items cheaper on-line, but by supporting your local shops you have the ability to help others in your area stop analog's and become vapers by supporting their store and becoming involved with them and spreading word of mouth advertising.
Try as many of the local stores as you can as they tend to sell different vendor products as well. Most of my stores carry the same, similar e-cigs but carry different vendor juices. This is the way to find out what you like and don't like without having to order a bunch juice and it only cost's you gas money.
