According to online deals forum, Slickdeals, the only retailers left with anything left in stock are the ones carrying them at full-price. That means this deal is essentially over.
The site lists these as place with inventory left, as of 4pm EST:
But you don't have to pay full price. It seems scalpers have picked up the discounted TouchPad and they are moving quickly on Ebay. The regularly priced $499 tablet is going for around $255 on the online auction shop.
Granted, this is a far-cry from the give-away price of $99, but below $300 is still less than the $499 iPad, and Android based competitors as well.
Comparatively, the Amazon Kindle is $140, meaning slightly less than $100 more can get you a fully fledged tablet computer, but still save over competing brands.
