Multiple Product Landers are great when you want to give your customer a choice between several different products or packages on your checkout page. For instance, you may want to offer 1-month, 3-month and 6-month supplies of a product, and allow the customer to choose which they prefer.
The setup is essentially the exact same as the the setup for the single-product lander, with one notable difference.
1) Set the Lander Type as Multi Product
2) Checkout page shows Product Options
-Your checkout page will show all your campaign offers in a product selection area. This can be customized by your designer to fit your site's look and feel.
For more details about setting up this type of landing page. Please refer to the single-product lander tutorial.
