Michael Isn't it amazing that Amazon has so many items in stock and almost always ships and delivers them at breathtaking speed? For example, if you live in San Francisco like we do, the ordered goods sometimes arrive on the same day. This is particularly remarkable in America due to the vast distances, because to deliver an order so quickly, the corresponding goods must already be in a warehouse that is less than a day's truck journey from the delivery location. To ensure this fast delivery for items sold by third-party sellers on the Amazon platform, Amazon uses an interesting trick called "commingling." And this is how it works: As is well known, third-party sellers must actually store their goods in an Amazon warehouse of their choice so that Amazon can offer them for sale on their behalf. If a customer from a more distant part of the USA orders the items, it would take forever to ship them by regular mail. However, if Amazon finds that the same item from another seller is already located in a warehouse closer to the end customer, it sends the customer those goods instead, since it's the same item anyway, and the delivery is much faster and cheaper!
As I recently read in an article by the FinancialTimes, this leads to problems if scam artists send inferior goods to the Amazon warehouse. The end customer has no idea that the ordered goods are not coming from the selected provider X through Amazon, but indirectly from a scammer. To top it all off, the customer will not blame the scammer for any defects found later, but rather provider X, who will be left speechless! I have also read reviews of products that praise the item highly up to a certain date, but then suddenly turn negative because obviously inferior products are reaching the end customer. Amazon still has a lot to fix here; they better put a stop to this soon!
