I ordered at around 6am PST on 10/21. I, too, got some JAVAscript error at the final ordering page (after I submitted my order) and didn't get a confirmation via e-mail. I called Cameraworld the very same day and the rep told me that something was wrong with the e-mail confirmation server, and I should just wait for the invoice along with the package. Although the rep told me that the camera was out of stock, and it'll take about 4 weeks for delivery, I got mine yesterday!!!
However, after I opened the package I saw an invoice of $609.84 for this camera ($599.99 + 9.85 S/H). What is this?!!! On the very same invoice it showed that I've been charged twice onto my CC, once for $313.84 (which was the original $303.99 + $9.85 S/H), and then another one for $296.00. I just phoned Cameraworld and they said that this deal was an error, and unless I have any proof that I purchased the camera for $303.99, they can't honor it. The customer rep whom I talked to did not express patience and transferred me directly to Jeff, the manager. He wasn't available to answer the call so I left a message. Now I'm just waiting for his return call, and I may have to return this camera (minus the S/H fee).
One bad experience for me shopping at Cameraworld >=(
