[herbovedam]

I want to give a discount only on 1 type of product variant. I have made this variant from YMQ product options.

so the product option variant I want a discount only on  "No Unstitched", and not "Yes Rs 6000"

Currently discount is applied to all variant options. But I want it only one type.
