One of my posts this morning pointed everyone at B&N's electronics department, which at the time was one of the few places that had the TouchPad in stock. I turns out that B&N didn't have as many as they thought. I've now gotten comments from 3 readers who saw their orders cancelled. One posted the email he received:
Dear Valued Customer,
We are writing to you regarding your recent Barnes & Noble order for “HP TouchPad Tablet with 16GB Memory”.
Due to unexpected customer demand for this item, our inventory was depleted prior to your order being processed so we are unable to fulfill this item as requested. Consequently, we have canceled your order and you will not be billed for this amount.
You may see an authorization on your credit or debit card for the order, but please be assured you will not be charged. The authorization will be released in accordance with your bank’s policies.
We sincerely regret any inconvenience that this may have caused.
Barnes & Noble
If you still want a TouchPad, it's not too late. The HP website is supposed to get more TouchPads in stock later this week. You can sign up to be notified by email. And BestBuy are also supposed to get more in later this week. You might want to keep checking the BB stock tracking page for the TouchPad, just in case they show up.
