Catch it live on TV
ABC is airing the Peanuts crew's Christmas extravaganza on November 30, at 8pm EST. Even if you don't have cable, you should still be able to get ABC on your TV by using a digital antenna -- it's an essential tool in every cord-cutter's utility belt.
If you miss it on ABC, you can also stream the Peanuts special in HD on any of your devices via Amazon Video or Xfinity. And if all else fails (read: if you don't have those subscriptions), there's always the option to buy the special ($9.99 for SD, $12.99 for HD) on iTunes.
