I haven't seen any.
But I use to sell quality pierced body jewellery (not pieces I made - they are the type you'd pay a bit for at a jewellers) and I have so much left over. I can't be bothered selling on ebay any more, so was considering putting up a listing in the classified section for those who wish to use points to buy any. Most are for navels (all brand new).
I honestly wasn't sure if anyone would want any though, considering I live overseas - although shipping for that kind of item is cheapish.
