Why is the price in the app preview different from my store? (Essential Subscriptions app)
The preview in the campaign editor starts with a Sample product and example prices. A campaign can hold many products, so the app can't guess which one you want to see.
To preview a real price, click Sample product above the preview and pick one of your products. The preview then uses that product's price, with your discounts applied. If you pick a single variant, it uses that variant's price.
If your store has more than one language, click the globe icon next to the product to preview the widget in another language.
On your store, the widget shows each product's real price with your subscription discount applied. To check the prices, open a product in the campaign on your live store.
