Here’s something I do to save money for trips that started when I brought some coin banks home from a visit to England. These little banks were originally containers for caramels and shortbread that came in the shapes of double-decker buses and post boxes. Once the treats were gone, I made a display of them at home. But then I thought: why not use them to save money? I started using one of them to keep the extra coins I’d brought home from England. I reasoned this would give me some starter money to use on my next trip there.
An opportunity to buy a piggy bank happened when I was in Switzerland. I saw a really cheerful one and thought I could use it for the Swiss francs I didn’t spend. At this point I decided to build a collection of banks. And I might mention that they also make nice souvenirs!
So now I fill them with extra coins I’m saving toward future trips (this includes shopping trips). It works well for me.
