For me, it's random little things for the house. Not furniture, not big decor pieces — just the stuff you don't think about until you need it.
A few weeks ago I was looking for a tray and somehow ended up spending half an hour browsing all sorts of home accessories. Kitchen bits, storage items, decorative pieces, things I didn't even know I was looking for.
This was the site I ended up on:
https://99everything.com/It's the kind of store where you go in looking for one thing and leave with five tabs open.
Made me wonder if everyone has a category like that. What's the one home item you keep buying or upgrading even though you probably already have enough of them?
