I'd say the only way to guarantee you're getting the correct product is to buy from the manufacture's page itself. Anker for example, everything is sold by them instead of sold by amazon.

Also been noticing a lot less companies allowing amazon as a "trusted online merchant" for returns.

While KEH was great for used camera gear (I haven't bought new or used gear in ages so IDK how they are now), B&H offers an unmatached breadth. If anything I'd say that Adorama is a much closer competitor to B&H, although I'm loathe to buy from Adorama due to the incessant spam I get from them every time I make a purchase.

Yes on both counts. KEH is mostly used photo gear and they tend to be my go-to for that although, like you, it's a rare purchase for me. I tend to default to B&H but I'd agree their closest competitor is Adorama (although B&H's store in Manhattan is much larger).
