Wholesale pricing and minimum purchase quantities for products can be configured in X-Cart 5 using the add-on Wholesale.
Wholesale pricing is a way to offer multiple levels of pricing for the same product depending on the membership level of the buyer and/or the number of product units ordered.
A store admin can add a dependency for wholesale pricing for a product either on a specific minimum purchase quantity or a particular customer membership. A minimum purchase quantity is the least possible number of product units that a customer can buy at a time. If a cart contains fewer items than the minimum purchase limit set for the product, checkout is not allowed.
Before you proceed, make sure the add-on Wholesale is installed and enabled.
