The Ultimate Travel Hacking Guide - StumbleUpon
Referring to this quote: "On our example, this doesn't work because we are going from the United States to England and the English Pound is worth more than the US dollar. Additionally, the Iceland Krona is not worth less than a dollar. However, if we were going the reverse way, this would work. I've used this method when flying to New Zealand since their currency is worth less than the US currency." I want to bring up an important point about currency exchange that is often missed or glossed over: it doesn't matter one bit if the unit of the foreign currency is worth more or less than one dollar. Those examples are meaningless without knowing how much whatever it is costs in BOTH currencies and the current exchange rate between them. Let me provide an example without even using outside currencies. The item you want to buy is $100. Back to travel. The answer is that you have no idea until you check the current exchange rate.
