The "marketplace" concept seems to be a recipe for disaster. It's basically leasing out your legitimacy and goodwill as a vendor to businesses that wouldn't be able to pull off their own ecommerce experience. As others have said, when something goes wrong, they're not going to remember "Oh, marketplace seller biteme42069 was a rip-off, avoid them", they'll just blame Walmart. It's funny-- Amazon has managed to so squander their reputation that Walmart-- once the epitome of schlocky retail-- had managed to look decent by comparison. They had a strong enough nationwide logistics network that they could challenge the "but-but Prime 7-minute delivery" argument, and the direct nanufacturer connections to ensure they had authentic, controlled inventory. They could have been a more trustworthy choice.
