Has anyone used Powerdvdstore.com? I want to get a videos there that they do not have in bestbuy or walmart ?

I'm a little skeptical about this online website and i would like to know if any1 has used or at least tried out using that website. They have old tv complete series on dvd like The Wonder Years, Boy Meets World, Everwood, Doug, California Dreams and also Kung Fu the Legend Continues so if you heard anything from this website let me know.
