If you like Splendor and often play at 2 then Splendor Duel is definitely worth checking out. The new draft and new win conditions change things up quite a bit. I still like to go back to regular Splendor too though when I am in the mood for that pure Splendor goodness.

NerdzDay is an annual sales even by Gamenerdz, a US online retailer. It's very popular because they often include some very good deals and the store has a relatively low free-shipping threshold and an easy to use customer hold option (which means that they can can hold your orders until you pile up enough to qualify for the free shipping)
