I think at some point the idea is just to get the older stock out to make room for new. They are only losing some profit, but they can't keep old stock. The pre-sales generate interest and excitement and it gets people back into the store at least twice (once for looking/trying on, once to pick up). That may generate additional sales, possibly for new stock. At this price point for fashion it's the relationships that are huge, and getting people into the store is probably the most important thing. JMO.
So, how do we all feel about buying Chanel from eBay? I have seen a few pieces I've fallen in love with....[emoji177][emoji177][emoji177]
Makes sense.
Resale: I bought one item new with tags and was very happy with it. I always see things new without tags being sold and returned and feedback that they weren't really new. I'm squeamish about wearing other people's clothes. Although I just made an exception to buy something from someone I know. Do look at the sellers feedback for complaints. Also be prepared with a good tailor to alter it for you if necessary. I would only take the chance on something I absolutely loved. You know how hard it is to choose from photos at the boutique. You never know how something will fit. It's a risk because few resellers take returns.
