Discrepancies

I still remember one sentence in my bachelor's thesis, the topic of which was Taiwan. "The price level in Taiwan is higher than that of the Czech Republic." I never did any serious research about it, it usually seems pretty similar, although food and services tend to be generally cheaper in Taiwan.

Today, I went to buy contact lenses. I bought exactly the same brand, type and amount in the Czech Republic for 770 CZK (about 1300 NTD or 29 Euros). In Taiwan, it cost 380 NTD (about 220 CZK, or 8 Euros). And that was in a normal shop, while the Czech price is over the internet, i.e. that should be the cheaper option. How weird is that!?
