I have a Madoka Magica wall clock I won at some random Aniplex game show panel at Sakuracon.

Tshirts I picked up in Japan:
Kyubey "I will make your wish come true. Anything."
The squiggly SOS-dan Haruhi logo

Tshirts Ordered off the internet:
Green Wings of Freedom design from Attack on Titan
Yellow No Game No Life "I <3 Jinrui" the main character wears

Honestly that's about it. I don't have much merch. I tend not to collect much junk for anything.

I have the English versions of a few LNs and Manga.
SAO Progressive 1-3. The Isolator. Some Madoka Magica spinoff manga (Suzune, Tart, Homura's Revenge).
