Step 2: Turn On Use Local Currencies

1. From your Shopify admin, go to Settings > Markets.
2. Click on Manage beside the market you set up in Step 1 (or another of interest, such as International).
3. Click on Manage beside Currency and pricing.
4. Click on the Use local currencies drop-down menu and select On.
5. Under Currency (next to Use local currencies) ensure US Dollar is selected (so where local currency is not available, USD will be shown).

Step 3: Set Rounding Rules and International pricing

The features that you can use to customize your international pricing model depend on your store's Shopify plan.

2. Go to your selected theme, and select Customize.
3. Select your Header section.
4. Under localization, select Enable country/region selector.
