I do apologize for not getting back sooner on this matter. ECF posts have really fallen to the wayside as of late while I was clearing up matters with our nicotine...long story.
As Doubler go, just like with any liquid, we always use what we believe to be enough to flavor the end product, then it rolls down to personal preference, what may be "enough" for us, sometimes, is too much flavor for one person, and too little for another.
The second scenario is the mixer, who might perhaps make the mistake of adding too little or too much according to the recipe. It doesn't happen all of the time, but it does happen.
Also, we get DROVES of email, which is frequently hard to stay on top of, because we have our daily routine, which is why we offer more IMMEDIATE ways to contact us, which is by Live Help or by a Phone Call.
I guarantee that you will get a live person. Buy More Stuff is not the way I would have handled it. If you hear that, you let me know who it was and I'll remedy that.
I don't have a problem remixing your order, but ask that you call us please.
