Same thing just happened to me today. I ordered this morning; still haven't gotten an email and it's not showing in my order history. I did happen to print a PDF of my confirmation page just in case.
Did it list that price in both the email and the website or just the email? I had gotten some buy alerts for a couple sale-priced games that came back in stock yesterday, and the price in the email was jacked up, but the sale price on the GameFly site was still good.
