On your Website Integration, you may see some products or packages say 'Contact Us for Availability' instead of listing a quantity.
'Contact Us for Availability' will show should a product or package if:
There is 0 'In Stock'
Example: a product is fully 'Set Aside'
Example: a package required all 2 of a chairs you had in inventory, but one of those chairs was marked as ‘set aside’. The package couldn’t be fully ‘satisfied’ with only one chair. Instead of showing 0 available on the package, it defaults to ‘Contact Us for Availability’
Or, if that product was selected to not track quantities
