I have one of those Quaker Oat Meal cardboard round containers that I use. I fill it up, then I dump that into one of those large commercial size pickle jars. Ive paid for entire vacations for all of us out of that jar.
I used to also, not so much right now, take excess $1 bills and toss them in there. If I had more than say three or four, then I would take all the rest and toss them in the jar. It worked really well because Im always breaking bills ($5, $10, $20, etc) and then I never paid exact change so I always had tons of change in my pocket.
It adds up in a major hurry. Even when I was a bachelor it added up. One year with all the $1 bills I saved and the enormous amount of changed I had saved up I took a trip to Florida, paid for all the gas there and back, all my expenditures while I was there and still had money left over when I came back.
