Expiring today, using Target's Cartwheel app, you can get 15% off almost any electronic product. This includes items like GoPro cameras, FitBit wristbands, and Sonos wireless speakers that rarely have discounts. There are two caveats, first, you have to go into a Target store to get the discount, it doesn't work online. Second, it does exclude Bose, DSLR cameras, pre-paid cards, installation & service plans, which isn't a huge list. You can read more about the deal here. And if you have a RedCard, you get the additional 5% off as well.
