Best Buy always has more than Wal-Mart. If anyone goes to a Wal-Mart expecting to find what they want and can't find it, it's kinda their own fault imo. Shop elsewhere for your music like, y'know, a record store or at least something that's at least kind of a record store (i.e. Best Buy, etc. etc. etc.).
One of the drawbacks of living in a rural area is that if you don't want to go to Evil Empire Mart it's at least an hour drive to the closest town with more than one big box store or an actual record store.
Again, you have the internet. Regardless, my main point was that I thought it was funny that the original poster/others were expecting something to be at Wal-Mart of all places and were somehow disappointed when it wasn't there when we're talking about the furthest from a legit record store you can get, here. If it isn't extremely popular right this instant, good luck finding something there.
