Yes, I have noticed this in my area. There was an item at Target on clerance,
the other Target about fifteen minutes kept it at regular price. The one store is higher price on grocery items.
My son got the game boy advance when he was 4. He just turned 6 and we got him the DS and he loves it. The picture is so clear and bright it looks better then our tvs.
You can look around for the DS in bundle pack and it comes with a case and a game or two.
Good luck.
