Flat rate shipping allows you to charge your customers the same shipping fee, no matter how much they order. This shipping price strategy can benefit you because sometimes knowing that they are going to pay one set fee can actually induce customers to order more, because they know it is not going to cost them extra when they actually check out.
Add Tags to Products
Once you have added your products, go to SpringBoard's Store Home » Products and Pages and select your product. Click Edit and under Tags (Advanced), enter in a tag name, such as flatship, that will be used for all products that, when combined in an order, will have a flat shipping rate. Repeat this process for all products that will have this flat rate shipping price.
Add Shipping Prices
For each product that will have flat rate shipping, go to SpringBoard's Store Home » Products and Pages and select your product. Click Prices. Click Create Price.
In the Price List drop-down menu, select Shipping Price and enter in the flat rate shipping price that you wish to charge. Click Create. Click Move to Active Status.
Change the Type to Custom Calculation (Advanced). Under Calculation Settings, enter in the following code
7 * (quantity / tags['flatship']); but replace 7 with what you wish to charge as your flat rate for shipping and replace flatship with whatever you entered as the Tag for your products. Click Save. Repeat this process for all products that will have this flat rate shipping price.
A Note about Flat Rate Shipping
Shipping is charged on an individual product basis, not on a total order. In many circumstances, the flat rate you wish to charge is exactly what will be charged. For example, if a customer purchases two products with a flat shipping rate of $7, then each product will have a $3.50 shipping fee assigned to it. If, however, the division does not work out evenly, the total amount billed for shipping may be off from your desired rate (by a maximum of $0.01 per product). For example, if a customer purchases three products with a flat shipping rate of $7, then each product will also have a $2.33 shipping fee assigned to it, for a total of $6.99 in shipping fees.
