The best selection of single origin chocolate bars I've found online is at [Caputo's](https://caputos.com/chocolate/) in Salt Lake City. I buy Mrs Duck a dozen bars for her birthday and have them shipped. Caveat: Her b-day is in Winter, so shipping is viable then. Probably not as affordable as other options, but is good for a special treat. Some of our faves: Most offerings from Pralus Marou (Vietnamese) Manoa (Hawaii)
