Been doing it for years. Every day when we come home everything smaller than a ten spot goes into an envelope in our safe. When the envelope holds 100 it gets sealed. When we have 5 of those we go exchange them for tens and twenties.
You’d be shocked at how much you can put back that way.

Good thinking. Tens & twenties. Try buying milk and ice with a fifty and expecting change.
We’ve done the same thing. Nothing larger than a twenty.
