Oh, what the heck. A price haiku!
Eight and nine dollars
Bandwagon comes on weekend
Twelve dollars Monday
But since it's hard to make guesses in a haiku, how about $8 and $9 tomorrow, stall for the weekend, and then a big jump through $10 and $11 to hit $12 Monday.
(Note: Those of you who are astute will notice I just predicted prices will go up. That means you should probably sell now as I am frequently wrong in my predictions. Oh, except by putting this paragraph here I'm also predicting downward, which now won't happen. "But you must have known I was not a great fool, you would have counted on it, so I can clearly not choose the wine in front of me!")
