$50 should suffice.
21 days for a cup that depending on the size would cost aprox $2.50 per morning is a couple dollars over $50. Glad I only get a couple cups a year. lol
A medium size here is $2.05 with tax. Another reason I LOVE my Keurig.
I know in my area they currently are selling coupon books for 10 large coffees for $12. Plan on getting a few to put with gifts.
