Remember: Nearly everything is cheaper on the south side of Puerto Vallarta! At the moment the exchange rate in Puerto Vallarta is now hovering just under 13.00 pesos to one $1 US. Don't expect to get the best rate at 'Casa de Cambios' and the rate given at the hotels is probably the worst. With beach vendors and flea market places they will give you a lot less, as they have to go to the bank and change them to pesos. Some banks are now not exchanging dollars to pesos or, if they do, you must show your passport and are restricted to exchange $1,500 a month or $300 per day. Merchants have similar restrictions, so many will not accept dollars for payments over $100. Your ATM card will work fine here and there are many machines around town. They will give you your best rate, depending on what your bank charges for an International withdrawal. By withdrawing your maximum, usually about US$400 (the machine will show amounts in pesos and some are restricted to 3,000 pesos) you get the best exchange rate when including your bank charge. The ATM machines here add a charge between 27 pesos to 44 pesos, up to 60 pesos at the OXXO ATMs. Note. make sure your PIN is four digits, if it'e five digit, just use the 1st four digits, and tell your bank you'll be using the card in Mexico, or they may put a 'Hold' on it. ATMs are now even
