Why do I have a coin bucket?
The efficiency of effort.
I never count change, pay with change, or take change with me. Instead, whenever I get home I empty my pockets and put all of my change into my coin bucket.
Then, once a year, usually around December, I go to my local grocery store, and Coinstar the entire bucket, (usually to the tune of about $300-$400).
I don’t do it so much for the money (but hey, a few hundred dollars isn’t bad for ten minutes of effort); Rather, it’s something that saves me little time whenever I use cash throughout the year (which can be several hundred times!).
And for me, processes that save time and increase simplicity is a combination I’m always looking for.
