Increase the price only to the first unit of the product.
One-time fee option is an innovative new way of structuring the costs of purchasing goods or services. Unit purchase prices increase with each item purchased, up to a certain predetermined cost, creating a tiered pricing system based on quantity. The advantage of single-price options is that the price per unit decreases with increasing quantity, making them an attractive option for consumers buying in bulk.
One-time fee options give customers an incentive to buy more and enjoy an ever-decreasing rate for each subsequent product. It's simple, efficient and effective.
