Time is money; therefore, we have to be careful about how we spend it. I created this easy to use automation spreadsheet in order to be able to calculate the exact amount of each grocery item I’ll have to buy so they can last me for the whole month. This way I was able to make just one trip to the supermarket per month and buy fresh vegetables and fruit on a weekly basis. As someone who’ve worked for over 9 years in a supermarket, I know first-handedly that the more time and the more frequent you visit the supermarket, the more money you’ll spend on useless things and you’ll waste a lot of time messing around.
