Stopped by Dollar General last night to pick up a couple of coloring books and other things for the kids and noticed a whole section of Wii accessories.
For anyone wanting a white plastic golf club, baseball bat, tennis racket, gun, or steering wheel, our Dollar General had them for $5 each. None of them were Nintendo brand, or course. Also next to them was a "Wii/Gamecube" controller (white) along with "rumble" PS2 and Xbox controllers (off brand), all for $10 each.
We don't play much Wii Sports any more but I may pick up the gun and steering wheels just to have some generic backup spares.
