You can kinda tell when at the grocery store. Anecdotally, a lot of "bulk-comfort" foods like potato chips, sodas, flavored waters, cereals, ... about doubled in price but now most of these items are almost permanently "buy 1 get 1 free" (sometimes but-1-get-3-free, the "old BOGO"). It's no longer a one-off reduction every couple weeks.

Consumers must have reduced purchases but companies don't want to backtrack on the price, thus they're always on sale without actually bringing down the base price.

I wonder if that affects inflation measurements as I don't know if the inflation basket is calculated based on individually marked prices or actual consumer spending.
