Our Bulk Discount Now is unfortunately not compatible with direct-to-checkout buttons / buy now buttons as these buttons bypass the discounted draft order checkout our app creates.
In order for shoppers to get discounts from our app, they must check out through the cart.
We recommend hiding/disabling direct-to-checkout buttons on products that are getting discounts from our app.
If you'd like to see this feature added to Bulk Discount Now, please email support. Features are added in order of the level of demand from merchants.
