Maybe my tastebuds are different but I bought this at a local healthfood store and I'm not completely sold on it.  I tried it in my tea and it did leave me w/ an aftertaste...just like most sweetners. *shrugs*

Ex Input:
I love, and use the empty containers for medicine/advil in my purse, desk, suitcase. Also line with felt to keep earrings. Perfect little size to disguise small valuables when traveling and LOVE the mints. Tiny and powerful without burning my mouth.

Ex Input:
My husband just bought a Keurig coffe maker. In the box was samples, his favorite was Donut Shop. I ordered the 35 K-Cup for him. I was so disappointed, out of the 35 k-cups 11 were decaf, giving me 6 k-cups of each of the 4 flavors. I also ordered the Wolfgang Puck sampler, I got 12 flavors 4 each. How cool is that! I would order Donut Shop again, just not the sampler.
