Absolutely. Even though most bacon sold in stores is already cured and therefore preserved, its still a good practice to extend the lifespan of your bacon by freezing it. This is especially the case if you buy in larger quantities via the Internet or because of a sale.
If its already in its retail package, you may want to wrap it with aluminum foil or use a Zip-loc (R) freezer bag. If you have unused portions of bacon from an open package, again, wrap tightly in aluminum foil or Zip-loc (R) freezer bag making sure to remove as much air as possible from the package before freezing. This can keep bacon fresh anywhere from 6 - 12 months in your freezer. Another option is to take a package of bacon and separate it into several smaller, breakfast-sized portions (4-6 slices each) and then freeze these. You'll be able to pull a portion out of the freezer the night before to defrost in the fridge.
