Select the Requires multiples checkbox to require customers to purchase in multiples. Use this feature to ensure your wholesale customers are purchasing your product by the case.
In the example below, wholesale customers will be required to purchase in increments of 12 (ie. 12, 24, 36, 48).
Wholesale customers will receive a message in the cart if they do not meet the order requirements. The subtotal will revert to the retail price and the checkout will not be accessible until the order has been adjusted, as pictured in the example below.
