Volume Discount App not applying to cart POP OUT

[tk2022]

Hi there,

We are in the process of switching to a new volume discount app (Vitals) but when someone adds the bundle to their cart, we would like it to activate the Cart Slide out - not take them to the cart page.

The volume discount app that is NOT WORKING is applied to this product: https://topknotinc.com/collections/hats-test/products/casual-original

Any help as to why it is not activating the slider cart would be greatly appreciated.
