Just stating the facts:
A few months ago at my favorite grocery store, I noticed that the price of cheese had jumped two dollars for a three pound package - all but Swiss cheese. I decided to buy Swiss rather than the intended cheddar and save a couple of dollars.
The next time I went in, Swiss cheese had jumped two dollars... but cheddar had dropped back to its original price. I bought cheddar.
The next time, it was all priced the two dollars higher. I didn't buy any. Cheese is not a basic need, as much as I like it.
This time? It's all one dollar higher than the original price. I bought a package grudgingly. I will stretch it as far as I can. I won't buy any more until I really, really feel a need for it.
Will the price come back down? Serious doubts here. At least we have a pretty good idea that others reacted to the price changes the same way I did.
Oh, the games they play to find out just how much we'll pay. Sooner or later, we'll feel as if the new, higher price is old hat, and they'll raise it again, maybe just a little next time. Well, we can hope, can't we?
