Collection Add-ons are a set of products you can offer when someone purchases a collection (package).

These can be products that are only offered when purchasing the collection or products at a special price for purchasing the collection. The collection add-ons will be displayed when the collection has been completed.
Demo
To view a simple demo, view this gallery in the Sytist demo. Click on any photo and add the 1 Item Collection For Demo to cart by clicking the +cart icon. This collection will automatically complete and you will be prompted with the collection add-ons.
Photo Products -> Collection Add-Ons.
To get started, click the Create New Collection Add-on button and give it a name and create.
Once created, on the left side of the screen it will list all of your products from your product base.
Check the checkboxes next to the items you want to add to the add-on and click the Add Products button.

Setting the Prices
You have the option to set a price for an existing photo in the cart and the price if the photo isn't already in the cart.
- Existing Photo Price: The price for the product if the image is already in the cart for another product
- New Photo Price: The price for the product if the image does not exist in the cart.
When you are finished changing the prices, click the Save Changes button at the bottom.

Add the Add-On to a Collection
When editing a collection, select the collection add-on you want to add in the Collection Add-On area.

You can bulk change the collection add-on by checking the checkboxes next to your list of collections and selecting Batch Edit Names & Prices.

Notes
- If you are limiting poses in a collection and you don't want the customer to select an additional pose, set the New Photo Price to 0. However, you can set the New Photo Price at a higher price basically charging them for a new pose.
- If someone removes the original collection from their cart, it will also remove the add-ons.
- You can use the extra photo and extra new photo option in the collections along with the add-ons, but it would be best to just use one or the other.
