Earlier quoted context omitted.
I think there’s a discount if you allow commingled inventory (or a cost to keep it separate) which makes sense as Amazon has to track and potentially stock it in multiple warehouses
The comingled inventory actually is a good idea, just flawed. Go ahead, comingle the inventory but keep track of where each item came from so when the counterfeit is discovered they know where it really came from and don't blame the innocent supplier.
Amazon taking action against the vendor, and consumers blaming the wrong vendor.
When you order from Amazon Marketplace you can clearly see who you are ordering from, even if Amazon shipping the item. Consumers getting a bad product will then no only review the item but the seller with negative feedback even though the seller they bought it from may have done nothing wrong
