Yes I think, that they sell items, that have been used. I bought my Manhattan PM, and after a few days I have seen, that inside on the bottom was a stain, and when I had a look at the bag I have seen, that the handles had a "little little" patina. The handles wasn't so light like on my other new LV bags. I think, that somebody has return that bag after 2 weeks of using it.Bummer to hear.. it sounds like they are sending you items that have been used !! On paper it may look bad, but I mean, all those reasons are valid. And just because an item will get scratched, doesn't mean that someone else should do the scratching for you ! Why don't you ask her if they have issues with defective returns, or even with items arriving damaged, because you really shouldn't get pieces that are imperfect !
And I must say, that the SA's doesn't look very good, if someone brings back a bag. I have retourned a Danube, and the SA taked it and withoud to have a look at it, she has puted it in the drawer.
