Can I use negative numbers in Product Options?

The app does not support negative numbers in option value pricing. You can only assign positive values under Adjust Charge to add extra costs.


Shopify does not allow line-item properties or app-added charges to reduce the product’s base price. The app only supports adding extra charges (positive values) on top of the product price.
