For example INR 100 off on purchasing a item of XYZ brand of value 500 and above. I have Brand as an Attribute.
In the Cart there is 1 item of ABC Brand, 1 item of EFG Brand and 2 Items of XYZ Brand. Currently it is getting calculated on cart subtotal hence calculation is going wrong.
Ideally this should be considered on the line item total of the cart which have XYZ as a Brand. Don't know how to fix this.
