Unless it's sold by Amazon itself. Amazon is quite good at making sure their own inventory is never commingled with FBA inventory due to the risk of counterfeits infiltrating their inventory.
I remember reading an article recently that said Amazon will use FBA products and replace them to make shipping faster. Especially if Amazon itself is out of the product.
Does anyone have a link or remember what I’m talking about?
Just checked and the only counterfeit product I’ve received was RAM and it was sold by Amazon.com. The box was not similar to the original and contained a foil space blanket.
The best resource for this is the Amazon sellers forums. There are horror stories of sellers getting 100's of negative feedbacks due to co-mingled counterfeit products, even when they've opted out.
Fulfilled by Amazon, but was it sold by Amazon.com?
I've ordered a ton of stuff from Amazon.com, from electronics to foodstuffs, and never received a counterfeit. However, almost every FBA product I've purchased was sketchy.
