All great questions! Here we go:
We are located in Souderton, PA
All of our flavorings are manufactured and bottled by their respective companies. Each bottle is sealed after production and therefore has had the least amount of open air time possible for maximum fresh
We do have plans to expand. The ever growing list of flavors out there is daunting but we are currently working our way through popular TFA flavors and next up will most likely be Flavorah.
Two options for shipping right now are First Class and Priority USPS - Shipping in the United States only
Payment options are Credit Card, Paypal, and Bitcoin
Bonus: I personally have been mixing for almost 2 years now.
Hope this all helps
Thanks and enjoy!
