Increase the Cost of an Option
Section titled “Increase the Cost of an Option”Want to charge more when a customer picks an option, like engraving, gift wrap, or rush processing?
Infinite Options lets you add a price to any option value, or charge per character on a text field. You don’t need to create a Shopify product first, but you can attach one if you want an SKU or inventory tracking.

💡 How it works
Section titled “💡 How it works”Use Infinite Options to set a price for an option selection you create by simply adding a price, or add a price to a selection while also attaching a product for SKU or inventory tracking.

Section titled “How to Add a Cost to an Option”Want to Charge for a Text Field?
Section titled “Want to Charge for a Text Field?”When creating a text input option, check the box to add a price.

What if I’m using Product Bundling (legacy)?
Section titled “What if I’m using Product Bundling (legacy)?”Product Bundling always needs a Shopify product for each priced option, and that product must stay available on the Online Store sales channel. If it isn’t, Shopify shows a “Cannot find variant” error when a customer selects the option.
How do I know which one I’m using?
Section titled “How do I know which one I’m using?”In Infinite Options, go to Settings and refer to the Product Bundling section. If the Native Bundling setting is on, you’re using add-on pricing. If it’s off, you’re using Product Bundling (legacy).
Shopify Discounts
Section titled “Shopify Discounts”Add-on pricing is calculated after discounts, so the add-on amount gets smaller when the product is on sale.
See Add-on Pricing and Shopify Discounts for a full breakdown.
Common Questions
Section titled “Common Questions”Do customers see the add-on product?
No. The product does not need to be on the Online Store sales channel.
Without that sales channel, it remains hidden from your storefront.
Why isn't my price updating on the product page?
That’s expected. The price updates in the cart by default. To show it on the product page, add the Dynamic Bundle Price block to your product template. See Show price changes on the product page for instructions.
How does product weight work?
The add-on product’s weight is included in the order’s shipping calculation. If it shouldn’t affect shipping, set the weight to zero in Shopify.
Can I track inventory?
Yes. Refer to our guide for how to track inventory.
