Coffee is certainly not for everyone and I have found that I go through phases with my coffee intake and preferences.
1) I hate instant so I never have it = $0
2) I am more susceptible to the caffeine in coffee nowadays and restrict myself to 1 a day at most = low intake
3) It is cheaper in the long run to buy a sturdy machine and make your own once you watch a few videos on youtube on how to do this. I am talking about ground coffee not the pods which are so expensive the more you drink. By buying a machine and bulk ground coffee you can equal the cafes' low net price of 20c per cup of coffee (hooray to beating the insane markup!)
