Bundle Builder
Learn how to create a step-by-step Build Your Box experience with Rabbit Fast Bundle & Upsell.
Overview
Bundle Builder lets you create a multi-step shopping experience where customers can choose products from different steps and build their own bundle.
You can use Bundle Builder to create:
Custom product kits
Gift boxes
"Pick 3" or "Pick 5" offers
