We don't have joint accounts. Food and stuff for the house is shopped and paid for by whichever of us goes to the shops. There is no rota for this but it feels as if it divides up equally. We never do this type of domestic shopping together; it's so boring there's no need for us both to be bored.
We both spend a lot on books as the novelty of a Kindle has long worn off in preference for real books. I buy physical CDs and occasionally vinyl. He buys boxed sets of television shows I'm not interested in. We don't have Netflix or any cable tv or tv subscription service.
I spend a lot on haircuts but very little on hair products beyond a basic shampoo we both share.
I spend a lot on clothes but I always have done. Clothes are my hobby- they are far more than just something to preserve modesty or keep you warm. Some people go skiing or sailing or other sports which are expensive. I've always been interested in design. I love the V&A. Their exhibitions of couture clothing, shoes, wedding dresses and ballgown were exhibitions of beautiful articles and craftsmanship.
Maybe its because women are constantly being told they need to look better, be better, have better homes, lives etc and that usually involves buying stuff
My home is probably quite shabby. It's an old, listed property in a World Heritage site and I'm happy with that. It doesn't have to be spanking new and glittering.
I'm not sure I'm constantly told by anyone I need to look better. I don't buy or read any women's magazines and rarely watch television with adverts.
