Various media outlets including CNN Money and ABC News are reporting that Wal-Mart has slashed prices on the iPad 3, iPhone 5 and iPhone 4S, though Wal-Mart's Facebook page is only advertising a sale on the iPhone 5 and iPhone 4S.
Wal-Mart is reportedly selling the 16 GB Wi-Fi iPad for $399, though their website is only listing the 32 GB version for $499 as currently being in stock online. Another good place to find a deal on the iPad is Apple's refurbished store, which offers a 1-year warranty on their refurbished iPads. They are currently out of the 16 GB Wi-Fi version, but they are selling the 16 GB 4G version for $509.
Those that can't find the iPad 3 16 GB Wi-Fi version in stock at their local Wal-Mart might consider the iPad Mini, which costs $329 for the 16 GB Wi-Fi version. It may not be as fast as the iPad 3 or have the Retina Display, but it will still run all of the same apps. It is also a much more lighter (and thus more comfortable) companion on the couch or in the bed, great for reading before going to bed.
