They may price it differently, but it would still have to be a price that people would be willing to pay. The items they bought outright from me that were never on their website were not LUXE, but were what I consider nice mid-range brands. Theory, Trina Turk and Joie clothing. Kate Spade shoes. I was paid what I think was a very good price.
I think that the main reason that they do this though, is they need stock for their store/stores. I think they are choosing items that they think will be desirable to buyers.
I don’t know this for sure, I am just voicing what I think is going on.
