Do you have a backup bottle of any fragrance?

I've seen pics before of some stashes where backups of several perfumes are clearly seen and I realized that I have a couple, maybe a few myself.

Dossier Powdery Hawthorn, Dossier Floral Marshmallow and until I received my 100ml bottle, multiple travel sprays of Phlur Vanilla Skin.

Does anyone else have a backup stash of fragrances?
