My family's been 'beating' inflation mostly by not buying a bunch of useless crap we don't really need. As others have pointed out, though, that may not count, as we've, pretty much, always done that. One thing we occasionally need is clothes. Thankfully, my wife and teenage daughter are totally on board with 'thrifting' as their preferred means of buying 'new' clothes. Almost all of the furniture in our house was purchased used, either from CL, FB Marketplace, or a local thrift shop.
Another thing that has helped to soften the effects of inflation for us is that we 'rebalanced' our investment portfolio in fall 2018, moving ~$200K (all capital gains we didn't have in 2016) from VTI into a 120 year old brick row house in a LCOL, walkable, small city, with a great train connection to Amtrak's NE Corridor, i.e., Philadelphia, D.C., NYC, & Boston. Our housing costs are unbelievably cheap at only $700/month, including all utilities and RE taxes. Gas prices were up a lot in our area this past winter. We just shut off the furnace. If they want to jack up the prices, we can just stop buying their product all together. Looking forward to, eventually, cutting ties with the gas company completely by installing an electric, ductless, mini-split system for both heating and cooling, switching to an electric hot water heater, and also getting an induction range to replace the gas one we have now. Fuck the gas company.
In December 2021, we sold our Subaru Outback to CarMax for almost what we paid for it brand new in 2019. Now, as everyone around us is bitching about the high cost of gasoline and diesel, we're little affected, as we can easily walk, ride our bikes, or take a train to get wherever we want to go.
As has been mentioned by others in this thread, since we already had been buying almost all of our food from small, local, neighborhood groceries and farmers markets, we haven't noticed as much change in prices as others have been reporting. The $5.99/dozen eggs we've always bought from a local farm family are still exactly the same price. No inflation.
Another thing DW and I did to help offset inflation was to buy $20K of I Bonds. We even helped our teenage daughter to use $2K of her savings to buy I Bonds, as well.
Another way we've been minimizing the effects of inflation is by consistently living considerably below our means. Last year, we spent 2.5% of our investments, mostly dividends and interest. If inflation and stock market declines cause us to spend more like 3% of our investments in 2022, I'm totally fine with that. It's not going to make a difference in our lives.
