well, it's definitely a bootleg.
Anime on Chambers (The Anime Store) gets bootlegs in from some company called Gamer Cell in New York. The DVDs aren't the only bootlegs they have in that store though. Books, wall scrolls, all of their flat posters, figurines, plush toys, some keychains, and so forth are also bootlegged products. They also go through a lot of employees because the owner (James Anderson) makes unwanted advances toward many female employees and customers. Personally, I would stay away from that store. It's also attached to an Adult DVD store....... that's saying something.....
I would suggest Gimme Anime, Gimme Gimme Pillow Toast (When they are around), and Rainy Day Anime over Anime on Chambers. Well, not suggest actually, I would insist.
Anime On Chambers also purchases legitimate DVDs/Blu Rays from Best Buy and then marks up the prices on them. Honestly, you're better off buying many anime DVDs/Blu rays from Best Buy. Don't feel that you have to support Anime on Chambers just because they are an anime store. A lot of other stores also carry anime products. Game Plus+ outside of the Big Lots on Chambers has anime, Docs Games, Game Force, and even Mile High Comics have some stuff available. While Second Spin has a problem with carrying some (used) bootlegs thanks to buy backs, they generally have reasonable prices as well. Also, I get a 3DS Streetpass or two almost every time I go in that store. If you live closer to Greeley, I actually suggest Hastings for anime. They're great about it. If you're closer to Colorado Springs, I rather enjoy Rainy Day Anime. Also, if you're looking for a good anime club, there is a great one on Meet Up. I have trouble getting out to their meetings because of schedule conflicts, but the club is run by good people. There are also stores like Game On or Troll Country that have events that are worth checking out. It's possible to support the community and anime as a whole without going near stores like Anime on Chambers. The local libraries are also pretty good when it comes to manga and anime.
