Gas goes up $6 a barrel and gas prices spike 15 cents.
Gas goes down $20 a barrel and prices fall a nickel.
Somebody's getting screwed.
I wish somebody would do a comparison chart of per-barrel price and pump price to confirm my theory.
It takes time for the complete price drop to hit the local gas pump. Basically, the local gas station will charge you the price that was set when their tanks were filled. If they get a refill before their tanks run dry, they charge the average the price based on the quantity that was replaced during the refill. Eventually, you'll get the complete price drop, but it'll take a little time.
Here's what I'm seeing in my area. When I left town on July 21st, or 21st July, the average price in my area was around $4 per gallon. I just got home last night, August 7th, or 7th August, and the price in my area has dropped to the $3.64-3.68 range. That's a nice price drop...
