I bought a Kit Kat Chocolatory gift box large for 45 USD as a gift for our anniversary (my partner & me). The S&H was 25 USD.
It was OK, an interesting experience. Just not worth that amount of money (YMMV and the surprise effect was worth it). It contained about 5 different types of Kit Kat (maple & strawberry, green tea, butter, ..pistachio?) including 4 Sublime Bitter. The latter were, IMO, ace but I already regularly eat pure sprinkles and pure chocolate spread and I am already used to Belgian bonbons and German/Swiss chocolate. I bought it for the Japanese twist...
Strangely, a month or 2 after I received it (it was stored as a present, meanwhile) PayPal send me an e-mail that the payment wasn't claimed and I got my money back from PayPal (???). Peculiar experience.
