Field note / UK buyer guide
How to follow a source link without losing the item
A directory page, seller listing and agent product page are three different records.
Start at the directory
FansSheets is the recorded discovery source for these entries.
Keep the seller identity
A marketplace URL or item ID helps distinguish the underlying listing.
Verify the agent link
Only use an exact product-level AllChinaBuy URL when it has been observed and checked. None in this sample passed that gate.
