Turkish Lira Currency Exchange
Cash from an ATM
The most convenient way to get money in Turkey is by using your home bank ATM/cash card or a credit card in a Turkish ATM/bancomat/cash machine. Most Turkish ATMs issue only Turkish liras, but some will give you liras, euros or US dollars.
Of course, ATMs are run by banks, so there will be not just fees, but significant fees, perhaps 2% or 3% or more of the money you receive. ATMs are an easy, but expensive, way to get money.
If you want to exchange cash, plenty of places will do it for you, and it can be cheaper.
Currency Exchange Offices (Döviz Bürosu) are found in tourist, market and commercial areas. They offer better exchange rates than most banks, and may or may not charge a commission (komisyon). Offices in market areas tend to offer better exchange rates than those in tourist areas. Offices at international airports in Turkey tend to offer poor rates of exchange (for you; good for them).
Consider the Buy & Sell Spread
Besides exchange rates, a good gauge of the price you’ll pay to exchange money is the Buy and Sell spread that an office uses.
The spread is the difference between what an office pays to buy a unit of your currency, and what it sells that unit for to someone else.
A big spread means the office makes a lot of money on the transactions. A small spread means it makes less, and you get more.
Look for the office where the difference between Buy and Sell is the smallest amount.
Post Office (PTT)
Most post offices will exchange cash US dollars or euros, and the bigger post offices may also exchange other major currencies such as UK sterling (but no Scottish notes!)
These have the worst rates, the biggest commissions and the most cumbersome procedures, but a few specialized branches may be willing to exchange currencies lesser known than the US dollar, euro, sterling, and yen.
