In the SupaDupa platform you can change the formatting of money values as they are displayed in your store.
So for example if you are based in New Zeland you can have your product prices displayed in $20 NZD or if you are based in Canada it can be $20 CAD or if you are based in Hong Kong it can be $20 HKD etc.
In Settings > Payment methods
Under "Currency display format", you can choose between the Standard and Extended formats.
This is how it appears on the site if you opt for the extended format.
