I hope someone can help to clear up my doubts on the issue of "original defect/rejected perfumes".

There are many Malaysian sites selling such perfumes. These online sellers have been in business for years, their businesses & customers feedbacks are darn good. Their sites have similar explanations on what "original defect/rejected perfumes" really are :- 

[  Rejects can occur in the factory and also during or after sale...
1) AFTER SHIPPING REJECT- after shipping reject is one of the common rejects for all products. In most cases, it will only effect the packing (box) but not the bottle. Since people won’t buy any defect items at the counters as customers only demand for the perfect item even with the box, this rejected item will end up at the warehouse. Another reason why our products have no boxes...
2) FACTORIES REJECT- it would be impossible to produce products without reject. Most company (factory) only achieve 99.8% yield (output) where 0.2% is rejected e.g. 99.8%x1000000 = 998000 bottles. The rest are rejected (2000 bottle). Why they are rejected? It could be Scratches, wrong branding etc. These reject will never be thrown away. They have their own vendor for disposal. Since there are so many manufacturers for brand of perfumes, it will be enough for people like us to trade them... Factory reject outlet is no longer strangers among us anymore. Their stores are everywhere. Nike, Levis, Ralph Lauren and lots more branded items are selling there. Are they selling fake item? No, they are original and customer has no doubt at all. But it had been sold with lower price as they are rejected... ]

And the prices are unbelievably cheap. I picked up some examples from 1 of the sites:-

[  For Ladies :-
CHANEL NO 5 EDP 100ML - RM160
CHANEL CHANCE EDP 100ML - RM160
DIOR ADDICT 2 EDT 100ML - RM180
HUGO BOSS DEEP RED EDP 90ML - RM160
ISSEY MIYAKE FOR HER EDT 100ML - RM160
MISS DIOR CHERIE EDT 100ML - RM170

For Men:-
ANGEL FOR MEN STEEL FLASK EDT 100ML - RM180
AQUA DI GIO EDT 100ML - RM160
ARMANI CODE SPORT EDT 75ML - RM170
CAROLINA HERRERA 212 MEN EDT 100ML - RM160
CHANEL ALLURE HOMME SPORT EDT 100ML - RM160
ISSEY MIYAKE FOR MEN EDT 125ML - RM170
JPG LE MALE TESTER EDT 125ML - RM160
PACO RABANNE ONE MILLION EDT 100ML - RM180  ]

And there are other sites selling at cheapers prices (range of RM120-130 & even at RM100 on so-called Sales Promo).

A Chanel for ladies for about 60% less than the OTC price?? And some selling Chanel & Dior for men at RM130 ?? 

Are these "original defect/rejected perfumes" really exit or merely Replica/Grade AAA/Fakes ???

Frankly, I dont mind having original testers or even defected bottles as long as the juices are original. But i would be blardy pissed to get Replica/Grade AAA/Fakes. Thats the worst thing that could happened.
