Taking A Page From A Gas Station's Playbook

A week ago, a half-gallon of orange juice cost me $2. (The official, signed price was 2/$4.)

Yesterday, it cost me $3.50 (signed at 2/$7). Some of the bottles on the shelf had the same expiration dates as the bottle I'd bought the week prior — suggesting to me that those very bottles had their price doubled, presumably because future bottles will cost the store more, because of the freeze in California.

I wish this kind of predictive pricing worked elsewhere. Wouldn't it be great if, instead of waiting for a year-end raise for merit, I could tell my boss, "I think I'm probably going to work harder this year, so you'd better give me that raise now"?
