Thanks to @yyy for posting the contact page for the MOF in English.
This is infuriating for me. I got an e-mail from DHL last night that basically said to be careful with iherb purchases and I was confused about why they sent it.
I went ahead and explained a few scenarios regarding why -- especially foreigners -- may have to make multiple purchases from abroad per year and sent my e-mail off to the MOF. I read through some new? rules in Chinese, but didn't really get it. I don't know whether they are overestimating the number of home re-sellers or not, but this is going to hurt foreigners just trying to make life more bearable while away from home.
Living in Taiwan long term is difficult and the little things like this -- more major for some people -- begin adding up and personally I would have called it quits with Taiwan years ago if it weren't for fear of my cats dying during the airplane ride while returning home among a few other things.
