Staples has the K-cup packages for sale at $7 / 18 count box when you buy 3
boxes.
Thats $21 for 54 cups... not too bad, but it gets better.
Buy 9 boxes for a total of $61 and you can then apply the $20 off $60
cleaning/breakroom coupon found on the breakroom circulars. Thats $41 for
162 cups of coffee thats $0.253 per cup.... pretty darn cheap!
breakroom circulars are right up front at most stores. You can even call
your local store and if you have a friendly MGR they will give you the code
over the phone.

You may have to buy 3 of each kind to get the deal, but heck who cares as
your getting 9 boxes anyway! If that is a problem call in and place the
order they will override the 3 of each and let you Mix and match!
ENJOY!!
