UPDATE – Staples: Two 24 Pack K-Cups (Many Flavors Including Starbucks) Only $17.58 + Free Shipping (Only 37¢ Each)!
UPDATE#2: You can now use coupon code: 93918 to save 20% and the coupon works online! With this coupon code you can get K-Cups for under 37¢ a piece!
UPDATE: There is also a coupon for 20% off your entire coffee purchase coupon code: 14096 , but it is not working for these 24-pack K-Cups. It seems the reason is that Staples has these 24-packs categorized wrongly, but a few commenters have reported getting the coupon added to their order by a customer service member customer service agent. If you get it with the 20% off coupon that will make each K-Cup only 37¢!
Staples has the 24-pack K-Cups priced up to $18.99, but when you add 2 of the same flavor coffees to your cart the price will automatically be adjusted to $10.99 each, making it just $21.98 for both!
This works on many flavor K-Cups including Starbucks!
