When using the international Amazon integration, you will need to set up the proper currency for that instance. For example, if you are listing to Amazon Canada, you need to select Canadian Dollars under Settings > Channels > Amazon Options.
SureDone does not convert currencies, so when you go to list the product, it's critical that you put in the CAD price under the Amazon Price field for that instance.
If you are listing on Amazon US and Amazon CA, an example of the product set up would look like the following:
Amazon US (1st instance)
Amazon Price (amznprice): 20
This would show up on Amazon US as $20USD.
Amazon CA (2nd instance)
Amazon Price (amznprice2): 25
This would show up on Amazon CA as $25CAD.
