It has definitely changed my spending habits - in VERY UNEXPECTED ways.
(Background: We're very close to FI, if not FI, but I'm OMY'ing or 2MY'ing or more maybe.)
Prior to witnessing a rapid rise in prices of many of the things I buy, I had a very good memory of what the normal and sale prices of stuff were. However, when prices were changing rapidly, that quickly became irrelevant. At first, I was very frustrated that I had no more "feeling" for whether stuff was a "good deal or not" relative to their "normal prices." At some point, I basically just gave up, and started buying whatever I wanted, without evaluating if something is a "good price" or not. This mentality has kind of stuck with me now. I also have feelings of "prices seem to go up every few months, so I might was well buy whatever I want now anyway." I know it's not purely rational, but these are some of the thoughts that have gone on in my mind. I've become much more "spendy" than I previously had been (even more than what accounts from the general rise in prices), and that has stuck with me. We still spend a lot less than the income from I earn from the "day job", and we have a huge war-chest of investments. But my spending habits have definitely changed.
Edit: An anecdote from Walmart, yesterday, with my spouse and myself. There was an item my spouse uses. Prior to the recent inflation, the name brand item used to cost about $3.50. Now, the name brand item is $6.00. The store brand equivalent of that item was on the shelf for only $4.00. My spouse reached for the cheaper "store brand" item because it was less expensive. I asked, "Do you like the name brand one better?" Spouse said "Yeah". I said, "Just get the store brand one, then. We can afford it, and we only buy this item once every few months." So that's what we did. This type of scenario has been playing itself out all the time, in my mind over the past year or so.
