I wouldn't be surprised to if this was largely accounted for in supply side contamination issues. It appears that Amazon treats all SKUs identically, sourcing the closest one to fulfill and order, regardless of how that SKU arrived at Amazon.
A concrete example: No Starch Press customers are receiving counterfeit books when ordered from No Starch Press' Amazon store.
Even if this scam is caught, it's still cost Amazon money in dealing with the issue. (And cost legitimate vendors no end of frustration with legitimate customers receiving fake books.)
