You can create separate fees for different products in just a few steps.
From your Shopify admin, go to Apps and select Magical Product Fees.
Click Create Fee.
Select a method (we recommend Function Method for most use cases).
Give the fee a clear name like “Bottle Deposit” or “Oversize Handling”.
Select Product as the fee type. Then choose if the fee is a fixed amount or a percentage.
Select Specific products in the conditions section and click Browse to select the products you want the fee to apply to.
Click Save when you’re done.
Repeat these steps for each fee you want to create. Each one can be customized to match the right products and the same products can be used in multiple fees.
