The value of the dollar is the driving force behind 90% of our operating costs. Crew is paid based on USD, gas prices are driven by USD which trickles into everything else. Equipment purchases, tank purchases, engines, etc. etc. - all in USD - all imported either by us or a local vendor who then has a mark-up so he can make a profit.So my question is this for @Christi and @Dave Dillehay : What is your cost basis? Is it Dollars or Pesos? Since you are in Mexico, shouldn't it be in Pesos? Then the Dollar amount would be whatever the current exchange rate gives. Or you pick your own exchange rate like the restaurants and taxis do.
It's easer to budget my trips when you put your costs in Dollars, but, again, I think it should be in the national currency. I someone wants to pay in dollars, use the exchange rate.
Personally I do everything in cash so I can go either way. I keep the 1% to 2% foreign transaction fee that many credit cards charge. (Now we'll get all of the Schwab and similar card users chiming in that their card doesn't charge a foreign transaction fee -- Not germane). Bottom line - You're in Mexico - Use Pesos.

If dive shops charged a fixed pesos rate, we would all soon be out of business.
