I recently notice the app was working great for single products using Pfand – deposit fee & cart fee app which had fees included to them in multiple type fees.
But There might be cases where you have a bundle
let’s say 2 cases :
- 6 Bottle PACK contains 6 ‘X’ bottle , All have fees on them

2. 6 Bottle PACK / Bundle Contain bottle X,Y,Z, Only some ( X) of them have fees on them,others don’t (Y,Z)

To solve the above, there is a good news, It’s now easy,
Prerequisite
- Your store must have installed Pfand deposit & cart fee app
- You must have already created an Multiple fee using the app
Case 1 : 6 x Can bundle contains 6 cans, All have fees on them
- Go to products, Add a product variant
- Make sure to check the option to Size
- In the optiona values , add in this format
(Number) * Product title
So in our case it should be 6 x can bundle, the below image is a sample you can refer,

- Add variants with price , hit save.

Case 2 : 6 x Can bundle, Only some of them have fees on them
