Right now Staples has Free delivery over $45 and a coupon code for $20 off your $50 breakroom order!
Find the list of 24 pack K cups HERE. You should hit $52 with about 4 varieties. Add the coupon code 54557.
They are aware that the k cups are having difficulty with the coupon....click on "live chat" before check out if it doesn't show up on your order and they will fix it right up!
You will have an order for approximately 96 k- cups for about $32, depending on which you choose, or $.30 per cup. If you don't want to store that many, I like their brand of kitchen trash bags for $5 for 50! There are also paper towels on special.
