WB: Multi Currency Converter

We have 4 stores, and we had to choose this app. It has all the features we need, it's customizable, and it's free. - Rates can be automatic or fixed.
- Currency symbol positioning is fully customizable.
- Currency based on geo location.
- Rounding options are available, even removal of decimals.
- No limit for the number of currencies to enable. If it was the other apps, you could have half of the features you need, and pay for the other half. This one is free. Support has been very great as well. Very friendly and reliable.
