totally agree, technology could make this much more cost effective (or time effective). what's the best use of my time versus the cheaper option..
It's interesting running the numbers though. e.g. if it only take 10 minutes to get cheaper fuel, how much cheaper does it need to be for your time to be worth more than the UK minimum wage (£12.21 for adults over 21)
based on my maths (from above calculations) it needs to be about 7p per litre cheaper to justify the extra 10 minutes and for your time to be worth more, per hour, than the minimum wage.
I once had the idea to do something like this, though the intention was to pitch it to gas station operators as a way to keep their prices competitive (i.e. alert them when the station down the street drops their prices so that they can too and not lose business to casual price shoppers or, alternatively, when the station down the street raises their prices, so that you can too and not lose revenue needlessly) and learned that there are a couple entities, at least in the US, that have national data here. I couldn't even figure out how to contact one, and when I called the other I was essentially laughed off the phone by someone with a VERY New York accent -- it seems from context that their data is VERY expensive and used by Wall St. types, so the idea of some nobody from flyover country essentially reselling it to mom & pop gas station operators was funny, and out of the question.
