I stopped in at a bike shop, after a long (two year?) hiatus from cycling. I decided that instead of the nice new tool bag, I really ought to buy a spare tube.

The clerk remarked that they are not pricing the boxes of tubes, because of the rapid changes in the petroleum market, but it was $6.50.

I chatted a bit with him at the register, considered shopping for baskets or panniers. The total at the register was more than I expected (always is, isn't it?)

So we look over the receipt. The tube was $7.50. I told him that I didn't expect the prices to be rising THAT fast.
