Coinbase not currently allowing realtime purchases of BTC

I'm seeing this message when I go to the buy screen. Note that I have a relatively new account on their site.

Due to higher than normal buy volumes, we are unable to provide exact price quotes right now.

Instead of pausing buys entirely, we decided to give people the option to purchase bitcoin at the market price in a few days. Once your USD funds arrive, we will exchange them to bitcoin at the market price at approximately Thursday Dec 5, 2013.

Note that you can cancel your order at any time up until your bitcoin arrive from the transfer history page.

The market price of bitcoin changes frequently. Below are some recent prices to give you an idea. These do not guarantee what the price will be in a few days.
