Anywhere online is most likely going to yank them, a lot of sets have popped up on here. I believe one of our members sold the "box only" but showed the jarts in the last photo of the listing, I believe they sold for quite a bit but then ebay removed the listing from the listing history after the sale was complete, so they really don't want any evidence of them being on there. I've even heard stories of them getting pulled from CL but thats secondhand so I don't know if there's any truth to it.
I haven't heard anyone attempt any of the new selling apps like OfferUp, maybe try there. Otherwise good luck, it might be a challenge.
