Both are world-renowned e-commerce platforms, but there are some obvious differences between them:

Different positioning: eBay is mainly an online auction and shopping website, where users can trade second-hand items or buy new items.

Amazon is a comprehensive shopping website that includes various types of goods, such as books, home appliances, clothing, etc.

Different business models: eBay adopts the C2C (consumer to consumer) model, where users can trade directly with each other; while Amazon adopts the B2C (business to consumer) model, where sellers sell goods directly to consumers.

Different payment methods: eBay supports PayPal payment, and users can pay with PayPal accounts. Amazon supports multiple payment methods, such as credit cards, debit cards, Amazon gift cards, etc.

Different logistics services: eBay sellers need to be responsible for logistics and delivery by themselves, while Amazon provides self-operated logistics services. Sellers only need to send the goods to Amazon warehouses, and Amazon will be responsible for the subsequent delivery.

After-sales service is different: eBay's after-sales service is borne by the seller, and buyers can return or exchange goods after receiving the goods.

Amazon has a unified after-sales service policy. For example, Amazon's own products enjoy Amazon's after-sales service, while third-party sellers' products are responsible for the after-sales service.

The reputation evaluation system is different: eBay's reputation evaluation system mainly includes buyer evaluation, seller reputation level, etc., while Amazon's reputation evaluation system includes seller evaluation, product evaluation, etc.

In short, eBay and Amazon are different in positioning, business model, payment method, logistics service, after-sales service and reputation evaluation system. Users can choose the appropriate platform for shopping according to their needs.
