My Wal-mart had an entire shelf for them, meaning a labeled shelf in the electronics section with room for about 20 or so. Ever since November I have never seen more than 2 on that shelf. And I really doubt it's the same two DS's this entire time. I think they restock that shelf daily and by 10pm (the time I go to Wal-Mart) they have nearly sold out.
No doubt about it, those things are moving. Good news if your trying to find one, unlike the Wii which gets stocked rarely, DS stock is replenished much, much faster. Even if there is higher demand for the DS in your area, you should easily be able to get a raincheck on one or simply ask the store to hold one for you. I am willing to bet that if you did this within 48 hours you will have one in your hands.
