Keurig takes 20% off select brewers, K-cups, and accessories via coupon code "BLACKFRIDAY". Plus, these items net free shipping. That's the best discount we've seen from Keurig this year, although select brewers and K-cup variety packs may be significantly less elsewhere. (It's particularly useful on hard-to-find items and limited editions sold only at Keurig.) Deal ends November 29.
