Quick answer
Sale weeks are when counterfeit stock moves fastest, because a low price stops looking suspicious. Here is what to check before you buy.

For most of the year, an unusually low price is itself a warning. During 11.11 and 12.12 that signal disappears — everything is discounted, so a fake priced at 60% off looks normal.
1. Check the batch code, not the box
Packaging is the easiest thing to copy well. A batch code that traces to an importer record is not.
2. Compare against the brand's real size range
Counterfeits often appear in sizes the brand never made for this market.
3. Be suspicious of "imported, no box"
No outer packaging usually means no import trail.
4. Look at the seller's full catalogue
A seller listing every premium brand at a deep discount rarely has real sourcing for all of them.
5. Texture and smell are late signals
By the time you notice, you have already used it. Verify before, not after.
