Discuss how to save money.
I don't do it, no.
I think tricks of this sort highly depend on your individual brain and what things make it go, "Oh." And that tends to be slightly different for everyone, as different people are more or less sensitive to certain things or ways of framing an idea.
The next level of this is to calculate the amount you would need to have saved to support the cost in retirement. E.g. if you have a $60 annual cost, you need to save $1500 just to cover it for the rest of your life (following the 25x rule for retirement savings).
I tend to buy subscriptions at the yearly rate because it saves money over a monthly subscription (except Adobe...fuck Adobe). The affordability of monthly installments is bought, in a sense, by paying more over time.
So, no, you're definitely not alone.
It's also cool to do this with savings pots. When people have a hard time saving, they'll say things like "what's the point in saving £10 a month towards X, that's nothing". I usually point out the annual figure, since a lot of people don't think that way.
That said, personally I do this too much, and it can make it hard to spend and too enticing to save. But that's a different topic..
