Plus, don't forget that, to the extent you ever received a counterfeit, a seller's return policy is basically meaningless.
I will also add that I have NEVER, EVER seen a convincing fake of the Classic Noel line. Too many features to bother counterfeiting. I really, really doubt you would receive a counterfeit Classic Noel (particularly one that wasn't COMPLETELY obviously fake). It's not really a concern with this particular collection.
I do agree with mzedith, though - there is something more "fulfilling," if you will, about purchasing something directly from the store (in addition to the fact that you are assured of authenticity).
