Makes me want to buy accessories from a store or from Nintendo's online shop. I can't stand fakes! I must have the real deal.

That's why I always make sure my stuff is shipped and sold by Amazon.
If you have to buy from a Amazon "partner" make sure they have high ratings. It's really up to you to be smart about your shopping.

AFAIK Amazon doesn't sell nor ship Nintendo accessoires in the US. It is all handled through 3rd-party sellers there.

You're wrong. Take a look http://www.amazon.com/Nintendo-Wii-U-Pro-Controller-Black/dp/B009AFLXQQ/ref=sr_1_1?ie=UTF8&qid=1370276005&sr=8-1&keywords=wii+u+controller

Shipped and sold by Amazon.

So it's only the consoles themselves? Sold by 3rd party and partly shipped by Amazon? Strange...

Obviously the one with the contoured battery door is real.

Yeah Amazon lets some retailers store their merch in their warehouses. I guess that's the next best thing.
