So for years I've had the old cheap metal 4 bill cash box. Has 4 slots for bills and coins above. I'm sure you've seen it at any neighborhood yard sale. Well it's becoming a pain because we tend to have much more cash at our games so I'd like to upgrade to a 5 bill or larger cash box. I've seen the drawers that go with point of sale registers but I'd rather avoid those if possible. I'm needing something that locks and is portable and can hold at least 5 different bills. If anyone has any suggestions I'm all ears. Thanks!
