The biggest increases would likely be in the first half of next year...
FWIW, We do some of our grocery shopping at Walmart because it is the cheapest game in town and I’ve noticed price increases on a variety of items in the 12% to 25% range. Canned veggies, ramen noodles, yogurt, hotdogs, and so on.
I also tend to pay attention to sale prices, and I’ve noticed that advertised sale items don’t go as low as they use to.
I've noticed that, too, plus it seems the kinds of meat advertised are less beef, and more chicken, hot dogs, and fish from China.
At Ranch 99 Asian supermarket, one can’t get some imported stuff any more. It just disappeared from the shelves. In other cases, the packages have gotten smaller. I think the problem is that the exporter is used to exporting one size for all foreign countries, primarily the US. However the US dollar has been shrinking compared to other currencies, and they need to use that trick of making the package smaller to entice consumers to buy their product in the US, but they don’t need that trick in other export countries. So with some products they have just written off the US, at least for the time being.
At Safeway the cost of ground turkey went from something like $5 per pound package to $7.50 per pound package in about 3 months.
