That was my thinking too. Plus, I have a gazillion points, which will disappear when the store closes. So, I picked up the 13 Birds I was missing, which were also mostly the very oldest. I'd been very, very slowly picking up the pre 2006 birds, and now, my bird collection is complete.
I also picked up the Bee Swarm, which I somehow missed when it was released.
Surprisingly, only $20 actually came out of my checking account. My PayPal balance covered the rest (if it's not in my checking account, it's not real money?)
Now, I'm debating the Aviary, Aviary Poses, and Perching Places. But that will cost "real money."
