The price in the grocery store has risen as well—not saying I know why, but it has.
Yes, prices for produce are increasing. Nitrogen fertilizer, necessary for corn production, has more than doubled in price and farm diesel hit $4/gal. in my area ... I know because I bought 1000 gallons yesterday. That is up from $2.35 last year. Not to mention the fuel necessary to transport and deliver the food. Expect more increases before there is any relief.
