Price of petrol plummets

The cost of 'gasolina' (petrol) at the pumps has astonishingly gone down by quite a bit since the summer!  Last year and the beginning of this year the prices were rising for all types and it peaked at about 1.45€ per litre.  A few weeks ago I was amazed to see the price on the 'surtidor' (pump) showing 1.30€ per litre.

I have just filled up my little motorbike (it only costs me 5€ each week in petrol!) this evening and it was 1.21€ per litre!  I don't remember the last time it was as low as this and I'm certainly not complaining.

Something else to mention while on the subject is that over here there are lots of 'gasolineras' (petrol stations) that have assistants outside who put the hose in the tank for you during the day.  You can usually pay them if you are paying by cash but have to go inside to the till if you want to pay by card.
During the evening/night time there is never anyone outside and you have to go inside to pay.  At night you have to pay first and tell them how much you want to put in but during the day the pumps are usually open and you can put in your petrol first, then pay.

Diesel is about the same price as petrol over here which is worth mentioning as I've been told that in the UK, diesel is more expensive! 

What is the price of petrol where you are?
