It makes sense for Amazon to rein in third-party sellers. Amazon needs them to fill out the catalog and cover the long tail of products, but poor customer experiences damage Amazon's brand.

If I have to email back and forth with the seller before I can return a defective item, why should I buy on Amazon instead of eBay?
