200 gram block of Cheddar (Cathedral City) from Sainsbury 1.97 GBP.
So at todays exchange rate approximately 100 baht.
Import Duty - bit of a problem here. the nearest to accurate data I could come to was this..
Thailand no longer applies specific duties on most agricultural and food products, and ad valorem rates have been reduced in accordance with Thailand's WTO commitments. Nevertheless, import duties on some agricultural and processed food goods have an average tariff rate of 25.4 percent. Moreover, bound duties on many high value fresh and processed food products will remain high, from 30 percent to 40 percent, even after Thailand implements reductions required under its WTO commitments.
From this American Government 2008 report...
http://www.ustr.gov/sites/default/files ... _14611.pdfAssume the lowest rate of 25% & the price goes to 125 baht. I think most of the Major Supermarkets sell it for 147 baht a pack. So, if the duty is at a higher rate & considering shipping costs maybe not too out of line.
I do know that the price of Cheese rose when nearly all commodities went up, a couple of years ago. The price in the supermarket went up to about 169 baht a pack. So, it might be a large mark up, but it looks, to me, that the local supermarkets are actually following the global price.
