Bad Choice: Buying Milk in Bulk
If your family isn’t exceptionally large, two gallons of milk might be too much to finish before it expires. Pouring milk down the drain isn’t saving you any money in the long run. At Costco, you have to buy two gallons at once, which is often too much for most households.

Instead, consider buying just one gallon at a time from your local supermarket. This way, you’re more likely to use it all before it spoils, ensuring you get the most value for your money without any waste.
