After you have created products representative of the rewards and add-ons offered to your backers, you will need to add them to the appropriate survey pages. Go to Products > Collections and select or create the collection that you want to focus on.
If the collection type has been set to manual then you can search for the products you want to include within this collection/survey. If the collection type has been set to automatic then you can adjust the conditions of the collection until the desired products are included.
Reward products are automatically sorted to the appropriate position on the page, but you can arrange add-on products by your personal preference.
Click ‘view’ at the top of the page to preview your updates after saving.
Repeat this process for each collection/survey group as needed.
