Create a Sibling/Additional Student Discount
There are a few options for creating a sibling/additional student discount. Below are a few examples.
You can create a bulk discount that applies automatically when 2 or more of the same fee are added to the cart. Bulk discounts can be done as a flat amount or as a percentage off.
Bulk discounts automatically apply when the conditions of the discount are met.
With the bulk discount, you can set the amount to be per fee (attendee) or per order. By setting the fee to only apply to remaining fees the discount in this case would discount $25 off each fee starting with the 2nd fee. There is no maximum number of discounts that can be given with a bulk discount.
This particular discount will only apply to Adult registrations.
A standard discount code can also be used for a sibling discount. This method would allow you to limit the number of discounts that can be applied by defining the Fees Limit column. Additionally, you can limit the discount to specific pricing for the class if needed by setting the Pricing Types.
The Minimum fees column would also be used to define how many fees must be in the order for the discount to apply.
Using codes would allow you to make a code for additional discounts for when you want a different discount when 3 fees are purchased.
Note - only one discount code can be used per order. So you would want the discount to cover all additional fees.
The Buy X Get X discount method could also work if you would like to make a matched sibling discount. The Buy X Get X would pair purchases withing the same class and provide a discount on the 2nd fee.
Global discount codes allow you to create the code once and apply the same code to any or all classes you wish to have it work for. Using Global Discounts allows you to use the same code across multiple events for a sibling discount.
With all the same functionality of a Standard discount, this option allows you to create the discount once and have it apply to multiple classes, with the ability to add it to additional at a later time by editing the discount term. This method also allows the discount to apply if you buy two different classes in the order.
The honor system is just that. Creating pricing for when 2 or more registrants will be enrolled in the class and trust that your families will not abuse it. You can also make this Admin Only if desired if you prefer to handle this in the box office.
You can create an oon-the-fly or one-off discount on the admin pages if selling classes for your sibling discount. While this would mean that you have to create the order, one benefit would be that you can, then Invoice the purchaser, with the discount applied. Allowing the payment to be made online or via mail in check.
