Hey everyone, just a quick update:
Unfortunately Thursday night we dropped the main database/index the site uses to query pricing history.  We are in the process of rebuilding that database as I type, but it will take some time to get the 12 million+ records re-indexed.  The re-population began earlier this morning. (We didn't lose any data, it is just an indexing/population problem)
For those who cannot access the site via 
http://cardtarget.com it *should* redirect to 
http://www.cardtarget.com - if it doesnt, let me know. 
We are getting ready to launch an updated site hopefully in the next week or two.  I will let everyone know when it is ready - it has a much improved UI, and I removed the login requirement if you just want to see average sale prices.  (You will still need to log into get additional analytics, high, low, last, etc.)
As a side job that I pay for out of my own pocket, I am working as fast as I can.
Thanks for the heads up from everyone who alerted us!
Bob
