Looks like the real deal to me.
There's three days plus left on the auction - you would be amazed how many people bid at the last minute too sending the price right up. The seller has 100 % feedback and doesn't seem to be selling other perfumes....so if it were me, I would bid.
Saying that, you have to consider that the bottles have been opened- you don't know the state of the perfume inside- stale or otherwise , if it's ever been refilled with something else or just EDP etc...the 'what if' list goes on but it's a chance you take.
You just have to decide how much it is worth to you when you bid and leave it at that. These bottles are somewhat worth less than two similar sealed parfum bottles with boxes IMHO.
Just my two cents.
