If I remember correctly Kakao was 13 euros and Kon Tiki was 19 euros. I think the exchange rate then was a little over 1.2. So would have $7,20 higher at 1.2.
We went back to KT to look again and confirmed. Maybe they have gone down - I think Kakao is pretty much in line with other places, maybe a little higher, but it is worth a little more. And just so so I don't get shot - IMHO!
