I have always used Wizard Labs for my flavors, simply because it is where I was first told about, and for $1.50 each, why not?? lol I just ventured over to Flavor West for the first time and it seems like they are a much better deal. 4oz is around $6 or 7 on most flavors. Besides the fact that I would have alot left over if I got one that I didn't like, is there any reason you guys have for or against Flavor West instead of Wizard Labs?
