You might have heard of “inventory building”. It’s where you buy at a lower price and store the product product for use at another time.
Can that apply to gas in your car?
If your car tank has a 75 litre capacity should you fill it up when fuel is cheaper? The answer is yes! This technique allows your tank to become a hedge against a future price hike. Makes sense right?
But mathematically speaking, if you refill your tank after you’ve run through say 65 litres, only then will you have to pay extra.
When you top off your tank every day, when prices are lower, you might actually end up saving $2 to $3 per week, which multiplied by 52 weeks (per year) can amount to significant savings. A little change in your habits would help you save a substantially over time.
Plus you never run out of gas and you’ve banked a little extra dough whenever prices go up.
