Currency exchange in Greece

While traveling in Greece with smarTours (New York, NY; 800/337-7773, www.smartours.com) in November 2014, I found that I was always running out of small currency with which to tip the many local guides we had.

One guide told us that the best exchange rate we could get was at post offices. Sure enough, after showing my ID, I was able to exchange dollars for euros at half the fees of hotels and banks I had used.

Also, the fee was the same whether converting $20 or $300, so it paid to convert a larger amount.
