Bundle pricing is a popular shipping pricing scheme. It charges a flat fee for the first item, and then an additional charge for each extra item purchased. For example, a bookshop owner ships hardcover books at $5.00 for the first book, and $1.50 for every additional book in the same order.
There are multiple choices of cost types in this method, and each row is allowed one or more of these costs. However, each cost type is applied to the entire order, so any cost that is multiplied by the number of items in the cart will be counted towards all items, including the first one. The image below shows this scenario already setup:
Only one row is needed for this scenario. It has one condition and two costs, but the condition here is optional. In the example, the bundle pricing only applies to hardcover books, and the condition checks that only the hardcover books are included in this pricing scheme. The Cost column has two types included, but they look a little different than the example. The additional item cost of $1.50 is applied to all hardcover books, so the base fee must be decreased the same amount to account for it.
Let’s assume the customer has added 3 hardcover books to their order. For the item charge of $1.50, that would be $4.50. There is also the flat fee of $3.50 which brings the shipping cost up to $8.00. That would be the same as saying $5.00 for the first book, and $1.50 for each additional book. ($5.00 + $1.50 + $1.50 = $8.00)
Multiple Item Base Fee
In some scenarios, your base fee may include more than one item. For example, a salesman will ship 3 of his products for a flat $15 price. But if the customer purchases more than that, they will pay an extra $3.00 per item. The screenshot below shows the necessary configuration:
As illustrated above, this configuration needs two rows to work properly. The first row is for orders with 3 items or less, and it includes a simple $15 flat rate. The second row is for orders with 4 items or more, and it is where things start to get tricky. The customer is charged $3.00 for each item beyond the first three. This is accounted for by setting up the Cost ‘3.00 multiplied by Item Quantity’. However, this charge will be multiplied by all of the items in the cart, including the first three. Because of this, the flat rate cost will need to be lower, knowing that an extra $9 is already being added to the cost.
Let’s say a customer is purchasing 5 items. The quantity multiplier will add $3.00 multiplied by the number of items the customer is purchasing. This totals $15.00. It will then add the $6.00 flat rate to equal a total shipping cost of $21.00. This is the same as having a $15 flat rate, with an additional charge of $3.00 for each additional item after three. ($15 + $3 + $3 = $21)
