What is a tester?

"TESTER"s are the bottles distributed by the manufacturer with the intention of being used for demonstration purposes on retail counter tops. They come without a decorative box, (in a plain, unsealed tester box) and may have a sticker saying "tester", "demonstration" or even "not for sale"  Testers will comes as shown and described on the listing (some do not have caps, for example) They are brand new, and identical in scent to their regular retail counterparts.
