How can I show the base price on the collection page?
If your products in Shopify have a very low base price, or even are priced at zero, and the main part of the price is calculated by add-ons in the Live Product Options app, then you may apply the below solution to show the actual base price on your store.
Collection pages
The app does not run the price calculation on collection pages, this would require a lot of resources and slow down the page loading time.
Google channel sync
Sales channels are synced based on the product price in Shopify, the price of the app is not taken into account.
Solution
You can keep your product options configurations product price calculations unchanged, but at the same time you update the product prices in Shopify to match the initial price when the product is viewed on the Product page (so the base price + options price).
Example:
Base price: 100$ Options: - Size: 20$ / 50$ / 100$ - Color: 5$ / 10$ Price displayed on the product page: 125$
You then update the base price of the product in Shopify to the initial price on the page:

Next, enable the setting described below:
Deduct variant price from options price
In the App > Settings > Theme settings > Deduct variant price from price total


How it works:
Product variant price (base price) = 100.00$ Options price (all add-ons combined) = 150.00$ // When setting is disabled Total = 100 (base price) + 150 (options price) = 250$ // When setting is enabled Total = 100 (base price) + (150(options price) - 100(base price)) = 150$
With the setting enabled, only the difference between the base price and the total options price is added to the base price.
Note: this setting applies to all product configurations, only enable if the above calculation is desired.
Negative prices
By default the app never lowers the total below the product's price in Shopify. If you enter a negative amount on an option value, for example a "Without embroidery: -15" choice on a product whose base price already includes the embroidery, the total stops at the base price and the deduction has no visible effect on your storefront. The option value itself is saved correctly; it is the calculation that is floored.
Lowering the base price instead
In most cases the better setup is to price the product in Shopify without the extra, and to charge the extra as a normal, positive option price:
Instead of: Base price 65$ + option "Without embroidery" -15$ Use: Base price 50$ + option "Embroidery" +15$
The customer pays the same amount either way, and no special calculation is involved.
Enabling negative price calculation
If you do need option values that lower the price, negative price calculation has to be enabled for your store, there is no setting for it in the app. You can reach out to our support team to request the setting to be enabled for your store.
It is not enabled by default because a negative price that is configured incorrectly lowers the total of real orders. Once it is switched on, check your configuration on a test product before using it on the products you sell.
Not the same as Deduct variant price from price total
The Deduct variant price from price total setting described above does something different: it changes how the base price and the options price are combined, and it never lowers the total below the base price. It also applies to every product configuration on your store. It cannot be used to make a single option value deduct an amount.
