is amazon business price to be mapped as an item extended property or as a price by channel. if the latter is true, what would i indicate for the subsource
Just to confirm that your question and the ones that followed were all answered in the support tickets you raised.
But for any other customers who might have the same question, I would like to clarify that you can add the Business Price attribute in your amazon configurator attributes section. You can either map it to an item extended property value or assign a default value. (screen shot attached below)
If you would like to add it to an existing listing, please make sure that you Revise your configurator with the 'Add new attriubtes' option enabled.
