Just an idea. We get to choose the nicotine level on our juice. How about an option for flavor level? Depending on the atty I use, I would want different "strength" of flavor. I know I can do some DIY for flavor enhancement, but it might be very convenient to have options from the vendor. This would be especially helpful to beginners who are starting out on carto/clearo which can mute the flavor.
I too agree with Keeferes. I've been going through Mount Baker Vapor for the last several months and they will automatically allow you to choose your pg vg ratios and will let you add extra flavor shots for what I think to be a reasonable price. Some flavors are good just the way the come while others are so much better with a few extra shots. Also they provide the option of 3.6mg nic. while most others that i've bought from or looked at only go as strong as 2.4. I like mine stong. any way, the extra flavor shots do definitely make a difference.
