I saw that you said that some of the sample sale bags are outlet bags? Is there a way to tell? There's a bag I'm almost certain is an outlet bag, but the description doesn't say so.
I think the outlets are a mix of made-for-the-outlet items and overstock of retail items, which may explain that. Do you see the bag on any other websites? That would be one indication that it wasn't made specifically for the outlets.
I own one just like it in another color, so it's hard to compare with other sites. Mine has a different tag though. It doesn't have the spade on it. I used to think that was a sign that it was an outlet bag. But maybe they're just moving to that tag.
