Example Input: For those of us with celiac disease this product is a lifesaver and what could be better than getting it at almost half the price of the grocery or health food store!  I love McCann's instant oatmeal - all flavors!!!  Thanks, Abby

Example Input: You can't beat this deal! 3 Boxes of 16 K-Cups for little more then $20. No other store can even match that price for Hot Chocolate K-Cups. Your normally going to be paying around $12-$16 for 16 K-cups alone. This package give you 48 K-Cups for a great price.  The Hot Chocolate itself is great tasting and can be used on mostly all settings for the B70 except for the travel mug. Low in calories and great tasting. Defiantly a must have if you own a Keurig brewing system!
