Amazon Warehouse Deals is my new favorite place to pick up K-Cups. Normal warehouse price is $16.99 for 48, but they have 48 Coffee People Donut Shop Medium Roast Extra Bold K-cups for $13.99, no tax for most and free shipping for those with prime (or two orders). Note that the expiration date will probably be 2-3 months away.
