Where can I find free beginners lessons in tai chi?

I would like this to be in video form,with step by step instructions.|||http://beauty.expertvillage.com/intervie鈥?/a>|||Ebay.|||Ebay thats a good idea, or for free try Utube, I picked up a video in a thrift shop a while back now watched it once, nothing beats being in a class. I bought the video to look good in the class to which i have never been back either, lol|||just go to your local WalMart or sporting goods store and look in the fitness section. there are tons of them. also youtube has some good ones.
