eBay allows the sale of food that is nearing it’s expiration date. Amazon does not. Amazon (Fullfillment by Amazon or “FBA”) requires that food items received at any of their distribution centers have a minimum remaining shelf life that is greater than 90 days. Items within 50 days of the expiration date at the time of arrival will be marked for disposal by Amazon.
