There's a saying always invest in a good bed and good shoes as if you're not in one you're in the other.
Personally I add -
Washing up liquid - original green fairy all the way here, BUT I never pay full price I always stock up when it's on offer. I've tried cheaper brands and even expensive other brands and they're never as good.
Kitchen knives I agree with. But oddly I've found certain brands of cheaper ones can be very good
Anything that is designed to keep you safe
Oh yes!
Perfume I agree with, mainly as I have sensitive skin and cheaper ones are murder for messing it up!
Conversely I've found cheaper skincare is better as less likely to have fragrance and loads of additives
Haircuts - I cut my own! Have for years. I find it very difficult to find hairdressers that can cut my hair how I like.
Legal advice when you need it. Ditto financial advice.
Definitely! I've rarely needed this but when I have the difference is extraordinary
Cars - I dunno. The bangers I've had I loved as I felt they were full of character. The top range ones we had while ex and I were together were ok but they were a constant drain financially with niggles and I didn't feel they had much personality - which may just be me being weird about cars. That said I have a milestone birthday next year and I have...toyed with the idea of hiring exes dream car for a day/weekend if only to wind hell up outta him!
(he would seriously lose the plot if I did!)
Peace and privacy!
Omg yes! If I ever come into serious money I'm buying a house in the middle of Fucking nowhere! With decent wifi admittedly. No neighbours, no cold callers... bliss
Condoms - yes! The consequences could be VERY expensive
