The Kaching Quantity Bundles app inherits many settings from Shopify. This integration helps maintain consistency between your product details and the quantity bundles app/widget.
Currency formatting
To change currency formatting, change it in Shopify.
In your Shopify admin, go to Settings > General.
In the Store defaults section, click the ... menu, then Change currency formatting.
Change the HTML without currency field. The Kaching Bundles widget uses this format. It does not use "HTML with currency".
Click Save.
For example, {{amount_no_decimals}} removes the decimals, and {{amount}} USD adds the currency code after the price.
Refer to this official Shopify article to learn more about the currency formatting options:
Prices in other currencies (Shopify Markets)
Shopify's currency formatting changes only your store currency. When a customer sees your store in another currency, Shopify uses its standard format for that currency, and the Kaching Bundles widget does the same, so the bundle prices match the other prices on your store.
For some currencies the standard format shows only $. Australian, Canadian and New Zealand dollars all show as $12.50, not A$12.50 or 12.50 AUD.
At the moment you cannot add a currency code or a different symbol to the widget prices for a currency that is not your store currency. The "Show currency codes" option in your theme settings does not change the widget. If you need this, add a vote or a request on our roadmap.
