VPCART allows you to provide more advanced discounts to customers in three different ways:
1. The first involves using different prices in the products table. With this method, you define customer groups and each group only sees the price field in the products table defined for that customer.
2. The second method is similar to the first, except you can specify a percentage discount across the whole shop for each group to receive.
3. The third method uses a table called customerprices. The customer will then only see these prices and not the prices normally defined for the products. Customer-based prices will add additional overhead. Each time a product is displayed, the customerprices table must be read to determine if the customer should see a special price for this product.
