The pump price has gone up! Yes, all the brands - Caltex up, Esso-Mobil up, Shell up and SPC up prices by 5 cents across all grades of petrol. Free market? Gee .... can you believe that?
My colleague introduced a site PetrolWatch http://www.petrolwatch.com.sg/ which primary function is to track pump prices and keep subscribers posted via SMS on any increase. It is a paid subscription to get the info and hopefully, you can quickly drive to the petrol stations of the other brands that are slower in increasing the pump price to make the investment worthwhile.
I think that is an interesting business model and I wonder if the site owner has recouped its capital on the web service and SMS gateway .... and also make profit after covering the operating cost. I don't think I would subscribe to the service as pump prices do not change on a frequent basis and I probably will not benefit much in the long run.
Would you subscribe to the service? Well, you would have to also consider the other functions of the website ....
