For a given SKU, Amazon commingles inventory, so who you bought from may not be the company who stocked the FBA shelf with the product. Surely Amazon can trace it back, but I think Amazon lost the "just a marketplace" defense a long time ago as a result.

Is the process of commingling inventory documented? That policy is slightly alarming. What would stop someone from sending boxes full of rocks to the fulfillment center with the sku of an iPad?

When you sell products through Amazon FBA (ship to Amazon, and they sell and ship it with the Prime logo), they give you the option to commingle inventory for most products if they have a UPC on them. They scan the UPC and then credit your account with 1 of the product. Your product is then mixed in with the rest [0].
