Amazon takes an extra 30% off a selection of Martinson RealCup Coffee K-Cups for Keurig Brewers via this clippable coupon. Plus, cut an additional 5% off and bag free shipping when you order with Subscribe & Save. That beats our January mention of an extra 25% off and is the strongest discount we've seen on these items at Amazon. A couple of best bets, with prices after the above discounts:

• Martinson RealCup Coffee Cayman Coconut K-Cup 24-Pack for $9.62 ($11 low)
• Martinson RealCup Coffee Dark Roast K-Cup 48-Pack for $13.70 (pictured, $15 low)
