Amazon keeps track of which seller's inventory it originally came from, so the right person will get in trouble if a fake is sent.

Actually not if the item is in commingled inventory. When the item is commingled, the seller does not place any identifying markings, such as their unique asin bar code, on the product. Nor does Amazon place seller identifying information on commingled items. They rely on the UPC at that point for automation.

No identifying labels does not mean Amazon doesn't know whose it is.

>Although products sent to Amazon as commingled inventory may be virtually pooled with those of other sellers, we track which seller shipped the units to our fulfillment centers from the time they enter our warehouse until they are shipped to the customer. This allows us to know who sourced the item that the customer received.
