My coffee habit was draining my wallet until I tried this...
I used to buy a latte every morning, costing about $5 each day. That added up to over $150 a month... I started making coffee at home with a French press, and now I spend only $20 on beans monthly. The difference let me put $130 extra into my emergency fund each month. It's been six months, and I don't even miss the shop drinks.
