TheDigitalNerds.com Would not fill web order, item still advertised on the web Internet

Twice I have ordered the camera on line at their web site and they accepted the order:

and both times they sent this e-mail the next day, all the while they continue to advertise the same item at the same price on their web site, and searchable on the web:

Dear: Vijay,
We thank you for your order and appreciate you shopping with us. Due to the product you ordered being out of stock for 6-8 weeks from today's date. We have cancelled the order. When or if we get the product again in stock soon will send you an email to place an order please do not resubmit your order again. Sorry again and thanks for your understanding

It is obvious that they have the camera in stock and they will sell at the advertised price only if you purchase other high priced accessories, which I dont need.

I will be happy to forward you the actual e-mails I received from them.
Thank you,
Yours truly,

Vijay
