Brooklyn Candle Studio International

This app saved us a lot of money on development. It is not an off-the-shelf solution, it will require their dev team to set it up. But they did so very quickly -- just a few days -- and they used a duplicated theme to avoid disrupting our site. We had one small tweak to make after launch, and they had completed it within an hour of our initial email. Highly recommend this one -- currency changes are not easy to do, and this seems to be working flawlessly for us, despite really complex requirements.
