I would argue that just like they bake in issues, you as a consumer have to account for that in your purchase decision.
There's no perfect answer, but i'm not sure you would be entitled to anything beyond them fixing the issue in a responsible manner. If you want something beyond, it's within your right to request that from them and theirs if they accept it. I will say, often if you have issues on individual packages with delays, they extend your prime by X days.
I don't buy on amazon very much, and I'm in Canada. But I don't see prices lower than Amazon frequently. Usually on other huge companies like best-buy or walmart. But they usually offer the same return policy and I'm pretty sure they face the same kind of scams.
But hey, that's my experience. You might have experienced something very different.
Imagine that mister Bezos start spending millions of dollars and employing an army to do deep-check into every item returned. Who's paying that bill? Amazon's stockholders won't. You will. I will.
But, as I said in a previous post, I'm not defending Amazon's behavior. I'm just pointing out that it's all about cost and the vast majority of users benefit from this as well (with lower prices and no-question-asked-return-policy), while a tiny-tiny minority of them might face an inconvenience of returning an used item from time to time.
The question is where does the discount from my doing their inspection for them go? It doesn't go to the prices, they're the same everywhere. It doesn't go to the shipping, that's my Prime account.
