I dunno? I just put my coffee powder into my machine, insert water, wait and boom, coffee. I also recommend putting cocoa powder into your finished cup of coffee, I call it the poor man's latte.
I'm pretty sure it'll come cheaper in the long run to get one of those coffee drip machines than to keep buying coffee packets. You dump those into hot water and mix, right? There's a lot of machines and you can just buy a used one for super cheap. All you need are filters and coffee powder/grounds/whatever and you'll get hundreds of cups.
The monies are part of our conugal properties now (。•̀ᴗ-)✧ It's okay bro, do you want to earn? Our sister @Ginko Biloba knows lots of ways ✧◝(⁰▿⁰)◜✧
