I think this is a good thread for sharing thoughts about how this experience has changed habits around spending. We're spending more on groceries, partly just eating more, partly because of shopping in more expensive places (Co-Op!) than previously (Aldi) but I've knocked that on the head now - I go in the evening, and there aren't any queues. I gave up drinking a year ago, husband has cut right down for weight control, or I'm sure that bill would have soared! We've added NowTV to the Netflix sub but entertainment costs are down because nothing open. We're all reading more, I'm writing more, these things don't cost money. No holiday or leisure travel costs. No salon haircuts and colour. No clothes shopping (not that we did much before, beyond replace what really needed replacing). Still buying birthday presents, but because we can't get together, the costs of big celebratory meals don't come up. No A levels, so no costs for extra tuition and crammer. Gym subscriptions suspended, everyone exercising at home or running/walking/cycling more. Husband WFH and that will continue indefinitely now, so saving on commute, but offset by better equipment for home office (decent chair, large monitor, will be getting a better desk and lighting). I can't get hold of new plants yet so I'm learning how to propagate from ones I have.
So yes, we are saving, and I am saving a lot; but I'm doing so in the expectation that my income is likely to fall over the next year, and my son is likely to take longer to find financial independence given the state of the economy, so I need to build up a buffer.
I think we will be changing some habits permanently and for the better. I'll give up my gym membership, because I've realised I can do as much for myself with home workouts. I'll go back to the hairdresser, but probably a third as many times a year, and I'll continue cutting my husband and son's hair. I'll double my hours volunteering. I'll be using my bike for more journeys. I'll be even less likely to buy new clothes or be extravagant with food. I'll continue to read, write and study more, and where possible I'll be doing these things for free, online.
But we will eventually be paying someone to do our bathroom, and fix the leak in the chimney breast, and do some electrical work, and I hope we'll be increasing our travel to visit family and just get out of the city and eventually, maybe, get on a ferry or the Eurotunnel and visit France again.
