I was meh about Wingspan but am thoroughly enjoying this sequel. Very easy to explain and get in to but a lot of fun to play.
The HOLD/MERGE order is such a great idea. The threshold for free shipping is fairly high, so it's hard for a lot of people to qualify for free shipping in a single purchase. But the HOLD/MERGE order comes to the rescue! It allows you to combine multiple purchases until you reach the free shipping threshold, as long as you are willing to wait until you've hit that threshold before getting your games.
I wish other board game stores would copy this great idea.
