Toys R Us has all fifth gen iPod touch units on clearance right now, offering a buy one, get one at 50% off sale.
As you can see from the images below (thanks @nickfruhling), the 16GB units are listed at $199.98 and 32GB at $249.98. Also on sale are iPod nano units too.
Stock is limited based on stores, so it’s best to call ahead to see if you can nab a couple of these. If you need a dedicated music player or an extra gaming device for the kiddies, you can’t beat these prices—if you can find stock available.
