Cilphex was correct. Coinbase has a daily limit that is site wide. So if other's make too many transactions they can essentially block you from making a transaction. I didn't realize that. It would be best if Coinbase gave the message before trying to make a purchase rather than after. Just posting to let others know. Here is the email response I received back from Coinbase:
Hi,
Sorry for the confusion on that! The limit you're seeing is Coinbase's daily limit being reached, not your personal limit. This is something we'll be raising in the very near future!
