Below are photos and descriptions taken by actual students who were tasked with finding economics principles in their hometown over holiday breaks. Textbooks tend to give the same boring examples over and over, but even students in fundamentals of microeconomics can apply the lessons they have learned on a truly micro level.
Records & Players
(Covington, WA) These two items are complements. There is no reason to buy records unless you have a record player or vise versa. Record players have very little to no value without the records to play on them. Both of these items alone are almost worthless but complement each other when they are together.

(Pullman, WA) This is an example of how a tooth brush and toothpaste are complements. People tend to buy a new tooth brush once they run out of toothpaste.
(Burien, WA) A tree and ornaments are complements because there is no other time in the year that ornaments will go with anything else. The ornament has little to no value when consumed alone but, when combined with tree or wreath, it adds to the overall value of the item. The ornament has more value when it is paired with its complement than it does by itself.
