Hello @Ole,
Those $5 bills that we occasionally come upon get put in a jar to pay for laundry. The communal machines in our building require increments of $5. So we like to have $5 and $10 bills available for that purpose. Beyond that, we are just about flush each month.
I will say that on our own behalf, we have been able to almost pay off a smartTV on a special offer of 6 monthly payments without interest. The only debts we have are friendly ones from people who accept $25/month to keep us in good standing.
We also just cut back to 'Broadcast Basic' on our cable TV service to save about $80/month. There are so many streaming shows for both education and entertainment that we do not miss all the bloody, gorry, gratuitously violent shows we no longer access. I highly recommend this as a way to save money for whatever your priority is.
