Quick Answer

When you buy from a third-party seller on Amazon, eBay, Etsy, or Walmart Marketplace, your primary contract is with the seller, not the platform. Platforms have buyer protection policies that may cover you if the seller does not fulfil the order, but terms vary. Always pay through the platform's checkout system, never off-platform, to preserve your buyer protection.

Online marketplaces have created a complex purchase landscape where the brand name you trust, Amazon, Walmart, may not be the entity responsible for your order. Understanding who is responsible for what helps you get resolution when things go wrong.

Platform vs. Seller: Who Is Responsible?

When you buy from a third-party marketplace seller, the seller is responsible for:

  • Fulfilling the order and shipping the correct product
  • Handling returns according to their stated policy
  • Product quality and accuracy of the listing
  • Any claims about the product

The platform is responsible for:

  • Providing the infrastructure and checkout
  • Enforcing its seller policies
  • Administering buyer protection programmes when sellers fail

This distinction matters when something goes wrong. Your first contact should usually be the seller. If the seller does not respond or refuses a remedy, escalate to the platform's buyer protection programme.

Platform Buyer Protection Programmes

Amazon A-to-Z Guarantee: Covers third-party seller purchases made through Amazon's checkout. If you do not receive your item or it is significantly different from what was described, you can file a claim. Amazon typically issues a refund if the seller does not resolve the issue within a set timeframe.

eBay Money Back Guarantee: Covers most transactions on eBay. If an item is not as described or does not arrive, you are covered. File a case through eBay's Resolution Centre.

Etsy Purchase Protection: Covers non-delivery and items not as described. File a case through Etsy's Help Centre.

Walmart Marketplace: Walmart's marketplace protection varies by whether Walmart is the seller or a third party. Check the specific seller's policies and Walmart's customer service for third-party disputes.

The Critical Rule: Always Pay Through the Platform

Buyer protection only applies to transactions completed through the platform's official checkout. If a seller asks you to pay off-platform, directly via Zelle, Venmo, bank transfer, or PayPal Friends and Family, you lose all platform protections and your credit card's ability to process a chargeback may be limited.

Requests to pay off-platform are a red flag for fraud.

When a Seller Refuses to Help

Step 1: Open a dispute through the platform's buyer protection system. Most platforms require you to contact the seller first and allow a few days for response before escalating to a platform claim.

Step 2: If the platform closes your case without resolution or you disagree with the outcome, dispute the charge with your credit card company under the Fair Credit Billing Act.

Step 3: File a complaint with the FTC at ReportFraud.ftc.gov and with the platform's seller reporting tool to flag the seller for policy violations.
