If you order at least 20 items from the same category in a single order, you're entitled to a bulk order discount.
The discount is based on the number of items, and their category. However, the product models within the category, and the print files used on the products don't have to be the same for each item.
Note that the discount is applied only to product prices, and they can't be combined with other discounts (e.g., volume discounts).
To get the discount, first you need to get in touch with our customer support team at Sales@CustomOneOnline.com , preferably with a draft order ready, to confirm the amount. Then you can submit the order (if you haven't already), and ask a customer support representative to give you a discount in the form of a refund.
Just remember that if the contents of your order change after you talk to the customer support for the first time, the discount might also change.
