eBay. You list, photograph, answer buyers and ship. Eligible bags go through eBay's Authenticity Guarantee automatically: you ship to an authenticator, who inspects the item, generally within 2 business days, before it goes to the buyer. eBay says it covers the cost of authentication14.
Vestiaire Collective. Listing is free; the 12% charge applies between $83 and $16,667, with a $10 minimum charge below and a $2,000 cap above, plus 3% payment processing2. Vestiaire also runs a page saying it takes no commission on over 4,000 eligible brands, with the 3% processing fee still charged6.
Rebag consignment. Rebag quotes a payout range upfront, lists the item within 5 to 10 days and pays 4 to 5 weeks after it sells. Its handbag commission runs from 32% up to $1,000 down to 15% above $9,0003. Rebag also offers an outright buyout and a trade5.
Fashionphile. Fashionphile makes an upfront offer and pays once it has received and authenticated the item, with free insured shipping. Choosing store credit or a Neiman Marcus gift card adds a 10% bonus7. There is no commission to compare: the offer is the payout.
