One of many author complaints on Amazon is they have no way to offer their books in bulk for classrooms, book clubs, etc. It would be a great feature to allow Shopify users to create some way of offering a 10-pack or 20-pack of their book as a single product (rather than the user having to add 10 of a certain book and trying to work out a specific discount based on price or weight).
Thank you for the feedback. Ultimately, we do not control how merchants price their products. I know Shopify has some functionality and apps that support, which appears to be what you are trying to accomplish - quantity based product discounts. We do offer you, the merchant, quantity based volume discounts on fulfillment.
