We don't have any Wally Worlds around here. IN fact, if it wasn't for this site, I woudln't even know what they are. But yeah, it doesn't matter what the name of the store is, if it's a chain store, chances are they have a SHIT selection unless you are into "best ofs"
by "wally world" do you mean Wal-Mart?
I buy the odd cd in a store, but I pretty much use ebay and itunes exclusively now. The selection is great and you can't beat the prices.
Amazon > eBay.
I'm telling ya.
