A healthy skepticism about authenticity based on price is always a good idea. But if all else looks authentic and you avoid buying only because the price is too low, you may miss out on some insane deals on authentic bags.
Either way, as a community service to all my fellow PFers, because I'm such an altruist and martyr ( ), I have appointed myself as the guinea pig who will risk funds to find out if these bags are indeed real. If not, I'm going to have a hell of a time getting a refund. But I'm up to the task
Ohhh our lovely guinea piggy, don't worry! The seller is in Italy, if you ever have problems I'll be happy to help you deal with the seller in case you feel you need it. So don't too much sweety altruist pink piggy.
