The purple “Sale” badge on Atlas product pages appears automatically when a product is on sale — meaning the product has a compare-at price set in Shopify.
If you’re not seeing the badge, it likely means the compare price hasn’t been configured yet.
How to enable the Sale badge:
Go to Products in your Shopify admin
Click on the product you want to update
Scroll down to the Pricing section
In the Compare-at price field, enter the original (higher) price
In the Price field, enter your discounted price
Click Save
Once the compare-at price is higher than the current price, Atlas will automatically display the “Sale” badge next to the product price on your storefront.
Tip: Make sure your compare price is meaningfully higher than the sale price to clearly show a discount to shoppers.
