I've had one since launch. I'm playing Zelda, Fast RMX, Shovel Knight: Treasure Trove, and Blaster Master...
... that being said:
So... someone at my local wal mart pre-ordered THREE of them for launch, and never came to pick them up. So, they had to wait 30 days before they could put them on the shelf. Well, that was today. I got there 30 mins before opening. Patiently waited in the electronics section for the employee to make their way to it.
When she asked what I needed help with, I explained the situation. She said they don't have them. I checked with an employee last night, and they were still in the security room. She walked back to "search" for them.
I have been checking twice a day, since Mar 4.
She came back and said she found them. She asked which one I wanted, and I told her al three lol. She said they can't sell blue items for more than one per person. I said that one person pre-ordered all three. /shrugs She said she would call a manager and clarify that.
After three calls to management, and no replies, she said "F" it. Sold me all three.
Two grey and one neon.

Just after she handed me the receipt, the manager arrived. He asked what she needed, and she explained. He said, "no, it's one per customer". I walked away with all three.
