My partner and I seem to differ dramatically when it comes to general spending. I do look for a good deal, but like to get better quality products, especially when it comes to food or hygiene products, for example.
My OH always goes for the super cheap version every time - then buys loads of them so we're stuck with the stuff for aages 🙄
Worth adding that we're both on very comfortable incomes. I get that it's good to reduce general spending so that we can enjoy other things, and maybe save enough to retire early etc... But does that really mean we must live like students in the meantime?!
