I was sent to China for business a decade ago. I assure you there is always a toliet paper shortage in Asia. (also a shortage of what most of us would call toliets) I was advised to take my own paper and I did not end up with a square to spare.
Yope, and if there is some, it is like sandpaper.
Sending toilet paper ahead of trip is a very good strategy, if you go to many countries. All communist countries for sure!
I am just worried, if, sometimes, in near future, people will have to send themselves toilet paper to America, before they visit.
