That may be because it is a strong flavor. I never use more than 2% in any mix I do with it. A little goes a long way with that particular concentrate, at least that has been my experience.I've been running out of my most used flavors (VBIC, Honeydew, Sweet Cream, Vanilla Swirl, etc) and a few others and just realized how the honeydew costs more than twice as much as the average flavor (in basically any size). Has anyone else noticed this?
I think I've decided that I am no longer going to be giving away my DIY honeydew to friends. I may have to start charging them the cost of the materials or just keep that recipe to myself ... yow.
