Did you know that some of the 75 feet versions of N-Strike Elite was shipped in the Phillippines? You might not agree, but I got one. That's my proof! So, should we report it to Hasbro or not? Pls. comment.
So you went to Toys 'R' Us, bought it, realized that the store having them was an accident (how do you know they weren't supposed to be there?), and you want to know if you should report it. Unless there's a legal issue or a recall, keep it. You paid for it. If it was really an accident, for a company to redistribute a few crates of inventory out of a country would likely be more of a hassle than it's worth anyway, especially if the items are selling.
Aside from the Rough Cut 2x4, there are also the 75 feet versions of the Retaliator. There are only few 15 meter, safe versions of the N Strike Elite. Wierd isn't it!
