This isn't about comingling, even though it doesn't make it any better. It's about the fact that outside of Amazon's grocery-specific operations (Fresh, Prime Now, and Whole Foods), Amazon does not have a mechanism for FIFO or any form of decision making based on expiration date. All decisions are optimized purely on fulfillment costs alone. As far as I know (I've been out for three years now), they have no plans to change this, as it would increase their fulfillment costs.
