Increasing food prices?

I goofed up my packed lunch today.  I mistakenly thought that a container of leftover Bolognese sauce was chili.  Oops.

On a hunt for something reasonably healthy and inexpensive, I went to a local Subway to grab a sandwich.  A flyer they had on display caught my eye, though.

I'm somewhat skeptical that the prices of tomatoes tripled overnight.  Yes, there have been snowstorms in the midwest already, but I have a hard time believing that tomato prices were teetering on the brink of a price hike but the last snow in Detroit made somebody say,"That's it!  We've had it!  Stop the presses!  We're tripling tomato prices, dad gum it!"

All that being said, if tomato prices really are considerably higher than they were 8 months ago, that's pretty notable.

And it makes me even more determined to get more into seed saving in the future.  If I can keep doing that, I'll be even more independent of external pricing.  Should I be able to grow in excess of what the family needs, then maybe we can take advantage of that.
