Amazon has this Keurig K-cup Storage Drawer (Hold 36 cups) for $14.99 with FREE Super Saver shipping and $25 purchase.
I love my Keurig, but finding away to store the K-Cups has been difficult. This may be the easiest and best way to organize because the drawer just sits below the machine.
Also, if you are looking for a smaller system (and some Ekobrew Cups), you can get this Single Serve Storage Drawer and 4 Ekobrews for $20.00 with FREE Super Saver shipping and $25 purchase.
Pricing was current when the post was published, however Amazon prices change often, so please check before you buy.
