Produce, meat, dairy and fuel prices fluxuate heavily with the markets. At Southern California Albertsons/Vons, in the spring 80/20 ground beef regularly went on sale for $1.99/lb., 90/10 sirloin for $3.99/lb and chicken breasts for 99c/lb. Ralph's (Kroger) never reached those lows (and now they're trying to buy Albertsons, which is the second largest pure grocer). Meat and poultry producers realized demand/ their prices were falling and have cut back on production, leading to prices rising once again.
You can still score some great deals -- since spring, Albertsons regularly has "inflation" sales where you can purchase canned or frozen steamed veggies, Haggen Daz ice cream cups, etc. for 50c each, peanut butter for $1, etc. But overall prices remain high. When those canned veggies aren't 50c, they're $1.50 -- they were 79c in 2019. When the peanut butter isn't $1, it's $3.99 (was $2.69). Then there's the bigger offenders... a 100ct pack of cheap paper plates went from $1.99 to a whopping $7.49. That flimsy paper towel that wouldn't be good enough for toilet paper went from 69c to $1.49.
Not sure about nationally, but fuel prices are on the rise here. My local Costco was $5.959 for regular this morning.
