I used to have literally a dozen Targets to choose from, back when I lived in MN -- the place where the store started. Now, in LA, the only nearby Target is pretty junked up and treated almost like a Wal-Mart. Pretty sad, because I love their stores.
The nearby CCs are hit or miss. I think, living in LA, that a lot of other CAGs get to the good stuff first sometimes, which keeps the selection less than ideal.
However, I've noticed Best Buys even slipping. The one closest to me has a terrible selection for both GameCube and GBA stuff.
Still, this is all nitpicking, since I've gotten some great deals from all of the above places. If we got an awesome deal every time we went into them, we wouldn't need CAG, would we?
