Mine arrived with a small dent on the top. I was able to push the dent out so that it's only noticable when looking from above. About the same as my Ni No Kuni strategy guide and Hyrule Historia--minor dings that I'm not exactly happy about, but I'm a collector who isn't uptight enough to go through a several-day customer service process to throw the dice on what might be a more damaged version in the end anyhow.
Now to see if we'll get a nice 3DS XL before the end of the year, or just cave in and get the standard blue one . . .
That's usually my attitude. I've gave Amazon free pass when my Adventure Time Season 2 arrived with damage to the slip case. I gave them another shot with the bent on AT:Playing with Fire. Project X Zone arrived with dents on top...Fine, I'm lucky to get the LE version.
Then MGS:Legacy Collection arrived and had dents on all side. The corner of the artbook got bent that it's really visible. Spoke with CS, and got only a $4.99 credit back. Whatever...not worth the hassle of shipping back to exchange.
Today, SMT IV arrive. The back of the case has a huge ing tear. Multiple dents all over that can't be smooth or bent out. A scratch running on the front of the case. Needless to say, my patient with Amazon is wearing quite thin over their persistance in using these bubble mailers. I'm returning SMT to Amazon and picking up a copy at Best Buy. I'll see if my BB copy is okay, if the guide is damage, I'll swap and sending the damage copy back to Amazon in their shitastic bubble mailer.
I've had Bluray sent back for exchange before too. The quality of their packaging has slipped since late last year.
