How do you know what cannot be faked? Is shipped and sold by Amazon enough?





All products can be faked, but I thing that GP means "cannot be faked without being obvious". Obvious fakes are not as much of a problem since Amazon has a pretty good return policy.

In the "cannot be faked" category, you can have:

- products so cheap that making a fake wouldn't make sense. for example an unbranded glass jar won't be faked because anything that looks like a glass jar but isn't a glass jar will be more expensive than a glass jar.

- products too complex and/or too low margin to be worth faking. For example, you will probably never find a fake desktop printer, as even the most simple printers are hard to make and sold at a low margin, maybe even at a loss. However, consumables are (very) high margin and you will find fakes, lots of them.

- products that have effective anti-counterfeiting systems. For example, Nintendo Switch games.


I understood fake as physically harmful.

It is, people are being ridiculous. The third party stuff is where the fraud is.

No, that is not correct or at least it has not been. Amazon was said to intermingle the inventory in the warehouses, mixing third party products with those shipped and sold by Amazon. So that gave you zero protection.

I read that they made internal changes to tag shippings properly to reduce the risk of that behaviour, but am not sure it is true or has been effective.


Has this co-mingling of sold by Amazon ever actually been documented at any scale beyond “extremely rare stock/pick” mistake? I am of course aware of the option for manufacturers to enable this for their registered products on FBA - and it may not have been optional at one point in time.

When I researched this a while ago I was unable to come up with much compelling evidence that it was an actual thing. It certainly has not happened to me over thousands of purchases - or anyone I know for that matter. Of course a fake could have been so good none of us could tell, but I do actually attempt to inspect carefully.

I have found counterfeit items from other web stores not on Amazon so it’s not like my detection skills are zero. Third party marketplace of course is different.

Heck, even Costco sent me an unsolicited refund for a counterfeit item they unknowingly sold me - so supply chain issues are bound to happen.

I don’t want to defend Amazon too much here, but this one is almost at urban legend status to me. Likely happened at limited scale some time ago, but it’s strange everyone says it’s endemic but no one IRL I know across probably tens of thousands of purchases has noticed it.


I don't think Amazon has ever outright admitted that they do, but Amazon's own terms give them the right to commingle their inventory with those of third party sellers.

F-4 Storage

We will provide storage services as described in these FBA Service Terms once we confirm receipt of delivery. We will keep electronic records that track inventory of Units by identifying the number of Units stored in any fulfillment center. We will not be required to physically mark or segregate Units from other inventory units (e.g., products with the same Amazon standard identification number) owned by us, our Affiliates or third parties in the applicable fulfillment center(s).

That combined with years and years of anecdotal reports of this happening certainly suggests a "where there's smoke there's fire" situation to me.


Right, that’s FBA. I’m talking about sold by Amazon. I’m specifically talking about a case where a sold by Amazon item came from co-mingled inventory from a FBA seller.

I also know from direct second party experience (I also personally saw the terms) that at least at a certain level of “brand” you can decline this option with Amazon for your registered product skus/ASIN even for FBA. I don’t know if this is offered to everyone though - I know it went through some sort of “deal reg” process in the one case I saw. I imagine this came through some sort of lawsuit or threats of one for a major brand at some point - but that is speculation on my part.


> I’m specifically talking about a case where a sold by Amazon item came from co-mingled inventory from a FBA seller.

The FBA terms I quoted specifically say that Amazon can co-mingle FBA inventory with their own (if the FBA seller doesn't opt out of "virtual tracking").


> The FBA terms I quoted specifically say that Amazon can co-mingle FBA inventory with their own (if the FBA seller doesn't opt out of "virtual tracking").

The wording in the quote explicitly states that an FBA unit can be substituted by owned by Amazon unit or other FBA units. But the wording is not clear whether SBA (Sold By Amazon) unit can be substituted by an FBA inventory. The terms covering Amazon's "first party inventory" (SBA, a.k.a. Amazon retail) are internal to Amazon and are not shared, AFAIK. But i can be wrong :-)


> The wording in the quote explicitly states that an FBA unit can be substituted by owned by Amazon unit or other FBA units. But the wording is not clear whether SBA (Sold By Amazon) unit can be substituted by an FBA inventory.

It would have to go both ways. If there are 10 FBA and 10 SBA units in the inventory, and Amazon decides to fill an FBA order with an SBA unit for operational reasons, now there are 10 FBA and 9 SBA units in inventory but the FBA seller only owns 9 units. That 10th FBA unit eventually has to go somewhere. The only options are that it fulfills an SBA order or Amazon forces the FBA seller to buy the SBA unit that Amazon shipped for the FBA order. As far as I know the latter does not happen.


But that has to go in both directions, necessarily. If they are not marked, as the terms say, they can't fulfill FBA from SBA but not SBA from FBA. It's all one big pile.

> It's all one big pile.

I don't believe this to be true. SBA in theory has it's own "pile" that they can of course use to substitute with a FBA third party seller if they deem it cheaper as they are confident that they are substituting like for like.

Given how FBA items are labeled differently (the Amazon required ASIN sticker) than SBA I can't recall a time I've received a third party item when buying direct from Amazon. I also can't really say with any certainty it does not or did not happen, but it was not obvious at least.

I've also seen contracts the explicitly forbid the co-mingling for brands that sell direct to Amazon. By necessity these would need to be under different piles on the backend - and it's easy to see different ASINs for the same SKU by searching for common big brand items. There will be a SBA listing, and then many other listings gaming the qty/size of the item that are FBA. An item that comes in the same size and packaging often is listed twice (or more) times with one being SBA and the rest third party.

It's definitely clear as mud, but I think the "sold by amazon/fulfilled by amazon" being co-mingled is largely urban legend. It's all speculation like this thread here, and very few verifiable facts when you dig into any of the reporting/social media accounts. I'm 100% sure it happens by mistake and very well may have happened as routine business in the past, but these days I cannot come up with an example that shows this happening on any scale.


I have absolutely bought multiple hard drives that were "shipped & sold by amazon" which turned out to be fake/counterfeit in some way. The serial numbers did not verify on the manufacturer's website either and they were completely DOA.
