They're still available. I think the link to the bricks can be found on-line at the www.disneyland.com website. I can't check it out right now because they have "too much traffic" on their site to process my request. Business must be good!
You also get a discount if you are an annual passholder.
<font color=navy>I think they run about $150 -- I don't know if that is with or without the replica you can get for your home. There is a kiosk in between the Disneyland and California Adventure entrances where you can order them.
