I do understand. Your dollars have lost value so you have to spend more of them to get the same thing. It's pretty simple.i think you need to go back and read my post with the pricing examples. as you can see, if they did that, your cost today would be less and so would mine. doing it the way they currently do it, your cost is the same but mine increases. why is this so hard for people to understand ? just because some do not understand, does not make the arithmetic incorrect.
Look at it from the other side; say a dive op charges US$50 for a dive and when we are there Canadian dollars and US$ are equivalent. We go diving and the op gets US$50 from me and $50 Canadian from you. Next year we go back; dives are the same price but now a Canadian dollar is only worth US$0.90. Do you think that the op should still charge you only 50 bucks Canadian? I sure wouldn't. You could change the US$50 to the equivalent in pesos and it wouldn't change anything.
