Date in Currency — Differences
6.30 in GBP — MC and Amex were exactly the same, Visa was 0.4% worse
7.1 in GBP — MC beat Amex by 1.2%, MC beat Visa by 0.2%
7.2, 7.3, 7.4 in GBP — MC and AMEX were exactly the same, Visa was 0.4% worse
7.5 in DKK — Amex beat MC by 0.8%

Norway — couldn't find anywhere that accepted Amex in Norway!

7.8 in NOK — MC beat Visa by 1.2%

Sweden — no Amex acceptance in Sweden, didn't even whip out my Visa I was so disgusted with it
