If you're interested in watching the reality show "Sister Wives," you have a few options. You can watch it on the TLC website, through a cable or satellite provider, or on Hulu. You can watch full episodes there, and they're usually posted within a day or two of airing on TV. However, you will have to sit through a few commercials. Hulu has a free trial, so you can watch a few episodes to see if you like it before committing to a monthly subscription.
