Custom discount solution
We faced challenges with the discount functionality since Shopify returned an incorrect Cart ID. After our investigation, we had to switch to the new checkout. Still, it was impossible to do so in all the stores as it would break the existing discounts on production since the new checkout extensibility doesn’t work with the old discount functionality. That’s why we’ve decided to move only one store to the new checkout, create a new discount feature for this store, then test it and deploy it to all other stores.
