Re: Best Buy
I purchased my copy of Summer Wars (Bluray) and Disgaea (DVD) from Best Buy. Though I have yet to see any K-On! Blurays available at an actual store, they have it listed online for some reason.
All in all, if you want your anime now instead of waiting for shipping, it's worth the little extra money to buy stuff from Best Buy. I am quite fond of how their anime section is growing every few months, however, the lack of Bluray titles is quite a dissapointment at times.
