Barnes & Noble still have the TouchPad (for about $101). I'm a little surprised to hear that; I didn't know that they carried it at all. In fact, this is the first time I ever heard of their electronics department on their website.
My local BestBuy sold out of the TouchPad in minutes, but they told me that they might be getting a shipment from the warehouse. No one knew when it would arrive, but they did suggest that I keep checking the stock tracking page for the TouchPad.
P.S. Keep an eye on this space (or my Twitter account). I will be keeping an eye on FatWallet, Twitter, and some deals tracking sites. I plan to update this post throughout the day as I learn of more deals.
