That's a really cool cap! I like the design on it.
The last thing I received was Girls-Pedia Vol. 4, went ahead and got Vol. 3 as well with it. Both very nice.
As for recent orders, I'm stupid and just ordered all of the NMB48 stuff for March 31 with the single through Amazon, which I peg to be:
8 Live Collection DVD
Chapuchapu Tour Blu-ray
the other tour Blu-ray
Team N 3rd Stage CD
A, B, C single
I would absolutely recommend anyone ordering any of the DVDs/Blu-ray to go through Amazon. You can save about 5000 yen on the 8 Live Collection alone, which softens the blow for other items if you're going that route.
This will be the first NMB single I'll be ordering through Amazon and subsequently the first since Oh My God! that I won't be receiving right on the release date. Suffice to say, it may be a restless couple of days.
