I have a pretty gold dish that I keep near my purse and my husband's wallet, in the hallway. We dump extraneous change in there when we come into the house.
Whenever it's full, I bring it upstairs to the master change box. It's huge!!
Whenever it's full, I wrap them up by hand and walk to the bank. It's some mental thing of mine: I don't want to spend money driving the car to the bank when the whole point of the trip is to save money. It's only about a 10 minute walk.

My main bank is about 30 miles away, so this account is what we call our dream account. We're not sure what it'll be for yet - maybe to pay off our mortgage, but probably to buy a large piece of land in the country on which we'll eventually build. We'll see.
So, our spare change funds only our imagination...
