Early in my working life my wage was $8000 p.a. I paid $40 once to recover the cracked vinyl seats in the car & thought this a reasonable price.
Spring forward 15 years, now earning $32,000 p.a: had a quote from the same upholsterer to pay $160 to replace cracked vinyl seat covers in another car.
I decided to fit seats from a wreck instead because it was more expensive than it had been last time.
But do the maths & each price was 0.05% of my annual wage.
