02 / HOW WE FILTER OUT BAIT SCAMS

The Two-Gate Arbitrage Rule

A low asking price on its own is often a counterfeit trap. Every alert on The Atelier Index must pass two independent gates:

Gate 1 (Above Scam Liquidation Floor): Listings priced below trade pawn/consignment buyout floor (e.g. a £1,500 Chanel Classic Flap) are automatically discarded as bait scams.
Gate 2 (Physical Authentication Channel + Valid Stamp): The listing must either qualify for physical hub inspection (such as eBay UK Authenticity Guarantee or Vestiaire Direct) or originate from an established UK boutique (Sellier Knightsbridge, The Handbag Clinic, Farfetch Pre-Owned) with a visible, era-consistent serial or date stamp.

03 / RESELLER NET MARGIN SPREADS

UK Marketplace Commission & Fee Benchmarks

eBay UK (Luxury Handbags £500+): Eligible for physical Authenticity Guarantee hub inspection in the UK; 0% buyer fee and competitive tiered seller final value fees.
Vestiaire Collective UK: Tiered seller commission (typically 12% to 15% + processing) plus buyer authentication/buyer service fee; high velocity on Celine, Dior, and Bottega Veneta.
UK Specialist Consignment (Sellier / Handbag Clinic): Direct cash buyout or 20% to 30% consignment commission for turnkey Knightsbridge/King's Road showroom placement.
