Last time I was there the woman in front of me in line asked about accepting Kohl's coupons and she was told no. I guess you could always ask at your BB&B though, you never know.
As a side note, coffeegiant.com has a great sale on k-cups now and there is always free shipping. All Green Mountain flavors are $3.00 off a box. I think it brings them down to $9.98 for a box of 24, as opposed to the boxes of 18 at BB&B or Kohl's. At the very least, sign up for their emails. They have new deals all the time.
