Around here, we've noticed quite a series of "ups and downs" in food prices this year. One week, the price on a given item is very high, but a week or two later, it's a bargain. Today, for example, we went to the grocery store, and had a head of lettuce on our list....however, they wanted over $4 for a head, so we passed....our last head, a couple of weeks ago, was half that price.
I place most of the blame on interruptions in production, due to the virus, And issues with delivery to the stores, as more and more trucking companies are having staffing shortages. Food prices are just One of the many things that this virus is screwing up.
