One listing looks fine. The seller's whole catalogue tells a different story: forty brands, all at a fifth of retail, all with the same photos, all listed this week. The listing is the bait. The catalogue is the evidence, and the evidence is what the buyer is supposed to read before clicking buy, not after the package arrives and the stitching comes apart.
A single listing can be faked well. A whole catalogue cannot, because the catalogue has to be consistent across dozens of products, and consistency at scale is expensive. A genuine seller has a pattern: a few brands, a coherent price range, photos that match the products, and a history that goes back months. A counterfeit seller has a different pattern: many brands, all discounted the same way, photos reused across listings, and an account that is weeks old. The SellerSentry guide on counterfeit electronics listings makes the point from the brand side: brands spot counterfeit electronics through price and seller signals, listing photos and specs that do not match the genuine product, and packaging and certification marks in test purchases. The buyer can use the same signals, before buying anything.
Start with the brand count. A seller carrying forty luxury brands at once is not a boutique. It is a warehouse, and warehouses that sell forty brands at a fifth of retail are not authorized dealers for any of them. Genuine resellers specialize, because authorization is per brand, and no one is authorized for forty brands at once. The catalogue that lists everything is the catalogue that is authorized for nothing.
Then read the prices. Genuine branded products listed new at a fraction of the authorized retail price, in volume, deserve scrutiny, and the scrutiny is the catalogue, not the single listing. A one-off bargain can be genuine: a return, a damaged box, a last-season color. Forty bargains at the same discount, all listed the same week, is not forty one-offs. It is a pricing strategy, and the strategy is to move volume before the account is shut down.
Then read the photos. Counterfeit sellers reuse listing photos across products, because the photos are the expensive part to produce, and a seller with forty brands does not have forty photoshoots. The VerityAI guide notes that relisters crop, mirror, add a border, bump the saturation, or paste the product onto a different background, and that visual matching still catches most of that, which is why image search is better than text search at spotting a relist. Run an image search on the listing photo. If the same photo appears under three different seller names, the photo is not the product. It is the catalogue.
Check the account age and the review pattern. A seller account that is weeks old, with hundreds of listings and a handful of reviews, is an account that was built to sell fast and disappear. A genuine seller has a history that goes back months or years, with reviews that mention specific products, specific delivery times, and specific problems. The review pattern matters as much as the count: a wall of five-star reviews in one week, all saying the same thing, reads like a campaign, not like customers.
Check the other channels too. A seller operating across platforms, with the same catalogue on three marketplaces and a standalone store, is an operation, not a person clearing out a closet. The Corsearch networks guide describes the pattern: multiple storefronts and changing identities, with a seller operating several accounts or storefronts to create alternative routes to customers if one is suspended. When a platform removes an account, the same underlying operation may attempt to return under a different identity. The catalogue is the thread that links them, because the same forty brands, at the same prices, with the same photos, will appear under the new name within days.
If the catalogue is suspicious but the listing is tempting, the test purchase is the proof. Buy one item, photograph the packaging, the markings, and the product, and compare them against the genuine product's reference: the serial or model details, the certification marks, and the materials. The SellerSentry guide recommends a test purchase file with photos, markings, and a clear statement of the safety and trademark issues, filed through the platform's brand protection channel, not the generic buyer complaint form. A test purchase that proves the product is counterfeit is worth more than a hundred suspicious listings, because it is evidence, not suspicion.
And if the test purchase confirms the fake, report the seller, not just the listing. File through the brand protection program for the platform, attach the evidence pack, and name the catalogue pattern: the brand count, the price pattern, and the photo reuse. A report that names the seller and the pattern gets the account reviewed. A report that names one listing gets one listing removed, and the catalogue stays up, with thirty-nine more just like it.
Keep reading: seller history checks before buying, spotting fake listing photos, and the authorised seller list check cover the nearby cases in this series.
Read the whole shop, not one listing. Forty brands at a fifth of retail, all listed the same week, with reused photos and an account that is weeks old, is the pattern of a counterfeit operation. A genuine seller specializes in a few brands, with a coherent price range and a history going back months.
Because photos are expensive to produce, and a seller with forty brands does not have forty photoshoots. Run an image search on the listing photo: if the same photo appears under three different seller names, the photo is not the product, it is the catalogue.
Account age and review pattern. A seller account weeks old with hundreds of listings and a handful of reviews was built to sell fast and disappear. A genuine seller has months or years of history, with reviews mentioning specific products, delivery times, and problems.
Yes. Buy one item, photograph the packaging, markings, and product, and compare against the genuine reference. A test purchase file with photos and a clear statement of the issues, filed through the platform's brand protection channel, is evidence, not suspicion.
