What to do with half-used bottles of perfume?

[KStockHERO]

I've got about five bottles of perfume that are half-used.

I bought them before Covid when I was an avid perfume-wearer. But since Covid, I've found perfumes really difficult to get along with. At the moment I'm using them as toilet spray 😬

Most places won't take them because they're half-used.
Any ideas for what I can do with them? Using them for post-poo spritzing seems a bit extravagant!

I would just give them away. Have you got any friends with teenage daughters? They would love them I'm sure.
I once had a few bottles I'd gone off so I gave them to the nursery nurses. They were sooo grateful :)

Bin them - they’ll have gone off by now.
