Buying a direct tv receiver box and card from ebay, will it work at home? - tv receiver

I have Direct TV in my house, but only for a TV and want another shot, if my wife can see another room. I have a few on eBay with an access card and was thinking about buying, but Direct TV charged me extra monthly? I must say that I purchased new receptors to activate?
