There are a billion for sale on Facebook right now. Literally as soon as they were released the Facebook groups exploded with posts. Some of them are not much above retail, I think people preordered whatever they could from this collection and then sold all but 1 or 2.
Since the collection has only been out for a little over a week, I feel like it's still too early to tell what inventory fell into the hands of resellers vs collectors. Per nicole0612, it seems like a lot of inventory hit independent resellers (private groups, facebook); then we see more items on eBay/PM/Tradesy; it takes 1-3 weeks for consignment sites to processes listings, so I have a feeling more items will pop up on FP, TRR, Yoogi's in the coming weeks.
It bares repeating, but if you're fortunate enough to be close to multiple boutiques, do keep an eye on each store's physical inventory as stores in NY really are receiving restocks and/or returns daily.
I guess we'll just have to wait and see. Most of the listings have been for the NFs which I knew was readily available online for purchase. LV can't really filter out the resellers when it's sold online. For the hard to get items that were sent to select boutiques, I felt it was rare to come across one on the the secondary market. At my local boutique, I was told by the manager that they had a waitlist for those who reserved the coeur bag but that she and the assistant manager were the ones who eventually decided who the bag went to. They knew the bag was limited and wanted the very few quantities to go to clients who have been loyal and appreciated the brand. The same went for SLGS from this collection (card holder, bandeau, etc..) Even with all the hype around the prism keepall, I felt like when it first launched, I saw sooo many on eBay. So far on eBay, I've only seen 2, maybe 3 coeur bag. On the 1 LV FB group (200k members) that I am apart of, I don't think I've seen any listed? None on FP, unless it sold immediately. And this bag is going for big bucks and if enough of them went to resellers, I think we've seen more available on the resell market.
ETA: I follow a handful of resellers on IG as well and have not seen any of them post any of the hard to find items. Again, the NF is the only one that I've seen. And these are the resellers who always seem to have a speedy nano listed every other week for premium prices.
