I've fallen victim to scammer merchants who use Amazon in their name. Before I would just check "Ships from / Sold by" under the Add to Cart button but it's not obvious if it's Amazon official. For example which one of these "Ships from / Sold by" is legit?
Two frequent Ship from/Sold by I got is Amazon and Amazon.com, and these items are non-link instead of 3rd-party which has clickable link to their front store.
