Direct answer: A proper test buy documents the listing before purchase with dated screenshots and seller details, uses a clean buying account and address unconnected to the brand, and photographs the item on arrival, packaging, labels, and side by side comparisons with genuine stock, before storing it sealed and labeled. Keep receipts, tracking, and correspondence together in a case file. That chain turns an opinion about a listing into evidence platforms, payment providers, and customs can act on.
Most takedown reports argue from photographs on a listing page. A test buy replaces argument with an object: the actual fake, in hand, photographed against the real thing. It is the strongest move a brand can make, and the easiest to spoil.
This guide covers how to run test buys that produce usable evidence: setup, purchase, documentation on arrival, storage, and how the file gets used across platforms and beyond.
Use a buying account and delivery address that do not identify the brand: no company email, no office address, no name a seller could search. Sellers who suspect a brand buy cancel, ship a genuine item, or quietly clean up the listing.
Capture the listing fully before buying: screenshots with dates, the URL, seller name and history, price, and claims made in the description. Listings vanish after reports, and your before record is often the only proof of what was offered.
Photograph the parcel unopened, the shipping label, the opening, and the item from the same fixed angles you use for genuine stock. Note tracking numbers, dates, and who handled the item, and keep every insert, tag, and scrap of packaging.
Then make the comparison set: fake and genuine side by side, same light, same angles, with the differences marked, logos, stitching, materials, serial formats, print quality. This set is the heart of every report the sample will ever support.
Seal each sample in a labeled bag or box with the case number, marketplace, seller, and purchase date, and log it in a register. Samples stored loose in a drawer lose their story within a month, and a sample without a story is just clutter.
Retain samples at least as long as the case and any related platform or customs action could run. Photograph everything so reports can be filed without reopening storage, and record every time a sample is checked out and why.
The same case file supports the marketplace report, a payment provider complaint, a social platform report if the seller advertises there, and customs recordation support where counterfeit imports are involved. File with the evidence pack attached rather than summarized.
Track outcomes per seller, not per listing. When a seller relists, the earlier test buy links the new listing to a documented history, which is what converts a routine removal into account level enforcement.

Start with the highest risk products and sellers: one documented buy per seller per product usually establishes the pattern. Repeat buys are worth it when a seller relists after takedown, since the second sample proves continuation rather than a one off mistake.
Yes, and it is useful information: it may mean the seller mixes genuine and fake stock, or identified the buy. Record it in the case file, keep monitoring that seller, and do not file a counterfeit claim the evidence does not support.
A neutral address unconnected to the brand, such as a home address of a trusted team member with permission, or a mail receiving service. Never the brand office: sellers check addresses, and an identified buy teaches them which listings you are watching.
Keep them while any related enforcement, dispute, or customs matter could still be active, commonly at least a year after the last action on that seller. Photograph and log everything so the file remains useful even after physical storage is cleared.
