I just used mine on a St Regis candle to give to my wife as a stocking stuffer to remind her of our most recent (now long ago) pre-covid vacation. Never in a million years would I have paid the listed $85 for it, but the $100 credit covered it all, shipping included.

It sounds like US members got the $100 boutique credit, while non-US members got a $50 giftcard, redeemable at any property for rooms/extras. Personally, I would have preferred the latter, as the boutique item list prices seem... "questionable". But not complaining.
