Gas prices

In May, just six months ago, I blogged about gas crossing the $4 mark. Last week, I paid $2.41 and it looks like prices are down a few pennies since then.

That means gas prices have dropped 40% in 6 months. I sure crude oil is down, but that's an amazing price drop. Has any good dropped 20% or even 10% in the last six months (stocks aren't really goods)? My gut is everything is MORE expensive now. Seems like a fake scarcity to me.
