Realistically, I need to go to Costco anyways, and I can buy these products in bulk as they have long shelf lives. Perhaps I spend 5-10mins extra at the store every 2 months, and another 5mins pouring everything in a large container together, once a month. So perhaps 10 minutes a month to save, say, 3$ a day, or 90$ a mo, works out to $360/hr tax free value creation rate without including the value of eating healthier, better tasting food. Where I waste my time is on reddit, HN, and video games.
