I have yet to be able to get K-cups any cheaper than this.  At Staples, they have a catalog that lists 24 packs of Kcups for 12.99 each and on the cover of the catalog is a coupon code for $20 off an order of $75 any breakroom supplies, which includes coffee.  I went into the store and their shelves had boxes of Kcups for 11.99 but for AN 18 PACK!  I asked a CS dude and he looked puzzled.  We went to the in-store kiosk where you can order things on-line but in the store.  Sure enough, the K-cups came up 11.99 for an 18 pack.  He called corporate CS and they were able to order me the 24 packs for 12.99.  I got 6 boxes 77.97-20q=$57.94 for 144 kcups.  Shipping to your home is free this week, but I think it's normally free anyway for orders over $45. I paid in store (if you have Green Mountain mfr qs, I think you can even use them, but I didn't).  Best part, they were shipped the very next day!  I think that coupon is good all year too.
