It wasn't very scientific I read about the harvests in Spanish newspapers on the internet, and my mom confirmed that prices there had more than doubled. I ran to the grocery store, and they were still selling it at the old prices. so I bought three gallons (enough to get me through until the next harvest). Neat arbitraging, I netted roughly $40.
For more specific data look at

"Grafico de evolucion de precios" is a long term look at prices, updated monthly, with a 3-month lag. For up-to-date information go to "Precios actualizados". No big changes in the last three months. It's in Spanish, with the prices in pesetas/kg for virgin, refined and shitty (they don't call it that), but should be understandable. The prices have come down a lot, but I don't think US prices fully reflect this fall.
(1$=140 pesetas, give or take).
