I rarely purchase coffee out now because of the cost but more importantly because of the ease and convenience of always getting a fast and perfect cup from my Keurig.
My go-to brand favorite is Newman's Own medium roast. With a savvy shoppers eye, I can sometimes get the pods for as low as .50 which makes me very happy.
Recently I had fun shopping and purchasing a few thermal coffee-to-go containers from Amazon. This came after I made the mistake of purchasing a $45 stainless steel to-go commuter cup directly from Keurig.com only to find that I despise drinking out of stainless steel.
Hacking Theater's article showing the math calculations prompted me to consider how much I am saving now by brown-bagging it. Working in NYC, the avg lunch is 8.00 to 12.00 so I'll err using a conservative $9.00 avg.
$9 x 5 days= $45 x 50 weeks = $2,250 a year
A sandwich from home with a piece of fruit and a bottle of water is $3.00 ( same for a lean cuisine etc)
$3 x 5 days= $15 x 50 weeks = $750 a year.
$2250- 750 = $1500 savings that will allow me to see at least 10-15 more Broadway shows per year!!
