I totally agree with RDC - that scenario is the exact one I'm imagining too!
Jade, nobody is saying you have to pay top dollar for a bag with PC lining in it! I've said before, in any case of authentication, it's ultimately down to what makes you comfortable. You're not comfortable with this one, and you've returned it and been refunded, as far as I understand.
So the fact that I've spoken up means that the opinions posted here are skewed? I hope that's not the case.
Actually, the seller will refund me when she receives the bag and is satisfied that it is in the same condition it was sold. I'll post an update when that happens

I am not saying that, what I'm saying is that people might think twice about posting a differing opinion to an acknowledged Bal expert, especially if they are not really familiar with FBFs in general. Heck, prior to buying a few of them, I don't know ANYTHING abt them either, other than what I've read here, and from checking out FBFs that belongs to friends.
In fact, I have Corey to thank for this very informative thread which laid out the differences between the 3 seasons of FBF! Thanks Corey, again, for your valuable input.
