When shopping for a particular good or service where there is no clear difference between them, go with the lowest unit price.
Example - gasoline. Most of us wisely buy the cheapest gallon of gas we can find because while there’s no appreciable difference between brands, there is a difference in cost.
And, when you’re at the grocery store, buy the lowest unit price groceries you can find. This works great for canned vegetables, frozen vegetables, shredded cheese, cheese slices, sauce packets, instant potatoes, and on and on.
Where there IS an appreciable difference in goods or services, consider overall value instead. Once I tried to use store brand barbecue sauce. It was HORRIFIC!!!
Lesson learned, right?
Other things where I appreciate value over price - toilet paper (Charmin Soft), soap (Dove), toothbrushes (Colgate 360), soy sauce (Kikkoman), and salad dressing (Ken’s).
So, where superior value is delivered, pay more. For everything else, buy the lowest unit price and pay less. When you do, you’ll set yourself up to complete the Mason Jar Vacation Challenge.
