Do you offer any discount on large orders?

A discount of 10% is offered when a customer buys 25 or more copies of a single edition; the discount only applies to that title, not to any others in the order. So, for example, if a customer buys 25 copies of edition A and five of edition B, 10% discount is offered on edition A, but not on B. The Shopify platform does not currently support this type of discount, so please contact me if you'd like to take advantage of this. An invoice can be generated if necessary, and payment can be made via bank transfer or PayPal.
