Pauly, I've thought that might be possible, but I've never seen an absence of them at the grocery store where we normally shop.
John, I don't think that fuel costs account for more than a few cents of the increase, so I imagine it also has something to do with supplies. I'm just guessing, but cargo ships are the cheapest means of transporting goods. I'm estimating we can truck something 3,000 miles for less than $.10/pound so shipping bananas here to California should be less. Plus, we're just looking for the increase from earlier in the year when I could buy them for $.29/pound. But your point does remind me of how there has been an absence in the news about large drops in grain prices in the past couple of months. Still, food prices at the consumer level aren't coming down. There were some articles out on that today. Here is one of them:
