No, Amazon mixes inventory. You should not trust Amazon with anything that is expensive or you put into your body. A product gets high ratings and is successful, then counterfeiters flood the market with a fake product that you end up inadvertently buying.

A recent example is Eclipse glasses that were purchased on Amazon. Since the inventory was co-mingled and Amazon doesn't have the time or expertise they refunded most purchases of the glasses both from legitimate and illegitimate sellers.

I believe this is only the case in US. If you're buying from Amazon in EU the stock advertised as "sold by Amazon" is actually their own stock.

Do you have a source for that? I tried finding an answer to this a while ago and was left a little unsure in the end.
