Amazon allows sellers to have a section on the Amazon product page which displays a set of bullet points.
You can map a field in ChannelUnity which will allow you to specify these bullet points on your listings if you wish.
What you need to do first is to either create a custom field** or identify a field you are not using in your online store.
You then use this field to populate the bullet points on your Amazon listing. Enter the text as a set of strings separated by the | character, so for example in the product field enter:
This is the first bullet point | This is the second bullet point | This is the third bullet point
Once the text entered into the field, switch to ChannelUnity and visit Setup -> Describe Product Fields.
Match Marketplace Field -> Bullet Points with the field used on the online store, under Your Online Store Field.
When uploaded to Amazon it would appear as:
• This is the first bullet point
• This is the second bullet point
• This is the third bullet point
** Note that Custom fields created in Bigcommerce are displayed on the product page and cannot be hidden
