Coach will not repair a bag you bought from a reseller.

No. If you did not buy directly from a Coach store or an authorized retailer (like their website, an actual Coach outlet, Nordstrom, etc.), the official warranty is void.

Coach’s warranty covers defects in materials and workmanship for the original owner. Once a bag hits a third-party seller—eBay, Poshmark, a thrift store, a consignment shop—Coach considers it a used item with no warranty left. They will not perform a free repair, even if the bag is authentic. They will offer a paid repair service (at their discretion, and it’s not cheap), but that’s not the same as a warranty claim.

If you buy secondhand, you are buying as-is. Save your receipts if you buy from an authorized retailer. If you want a repair on a resale bag, expect to pay out of pocket—if they even accept it.
