Where can I find/buy mini perfumes?

Other than gift sets at Sephora, are there other places that sell miniature perfumes? *Not travel sizes/ vials!! I’m looking for the little versions of the normal bottles :)

Preferably somewhere near Brickell City Centre, but I’ll check-out stores anywhere in Miami!

If not, my backup option would be looking for shops with cheap designer perfume dupes/ knock offs… if possible?
