"Buying cheaper versions of everything, even if you end up buying 2 or 3 in the same year.My gf wasn't as fortunate as I was growing up, and getting her to understand that it's worth spending the extra money on quality household items (pots, pans, utensils, toaster, etc) is much better down the line since they'll last you longer. She had a 30$ toaster that ended up breaking, she replaced it with the same brand twice and it broke again. I went and bought a 120$ toaster and it's been with us for over 3 years, no issues since."
