Tester means "sampler" in English. A Tester Perfume is a product that the supplier sells to display in the physical store.
The difference between a Regular perfume (normal, Non-Tester) and a tester is:
1.- The box: Instead of the traditional box, the tester perfume comes with a white or cardboard box.
2.- The cap: It may or may not have a cap, depending on the brand.
So that's why the price is cheaper compared to a regular product. It is a very advantageous option for those who want to have an original and quality product while paying much LESS. But since we don't have a store, the product remains NEW, SEALED, CLOSED.
