Is the price too good to be true? An exceptionally low price suggests a rogue seller who is either breaking MAP to win the Buy Box and/or someone selling low-quality counterfeits.
Is the seller marked as “New”? This can indicate an opportunist who has snuck into a listing to sell through product they acquired through retail arbitrage or counterfeit goods.
Does the seller name sound legitimate? How many seller reviews do they have, and what is their seller rating? The more reviews and higher the seller rating, the more likely they are to be a legitimate seller. If the seller has few or many negative reviews, it’s good cause for concern.
Is the order Fulfilled by Amazon? FBA orders are screened by Amazon warehouses. While this does not prevent counterfeit products from shipping to customers, it helps. If a seller offers FBA, it’s a good sign.
What else does the manufacturer make? Do they offer a full product line? This is another case where more is better.
Are the customer reviews verified and what is the average rating? Amazon was once rife with fake customer reviews. While measures have been put in place to prevent them, the problem still persists. You can use tools like Review Meta to assess how reliable customer reviews are in a given listing.A legitimate seller might have concerns for one of the above, but if they have multiple, your customers should do more digging or look into purchasing from another seller. As the brand owner, if you have good reason to suspect an illegitimate seller, you can report them to Amazon.
