There is sort of a loose "requirement" from the Office of International programs that says you should buy an ISIC card. It is supposed to be an international ID card that comes with discounts around the country. But I say, isn't my passport an international ID card? And the benefits aren't all that great in China. Most of the discounts are in Shanghai, only one in Nanjing.
It's $25, and I feel like it wouldn't really be worth it. Has anyone ever used the ISIC card abroad? Did you find it convenient? Would you recommend it?
