Sending Money to India

I used SBI http://www.onlinesbi.com/glsus/ to transfer money from my US Credit Union account to India Citibank Account. It worked pretty much up to my expectations. It took 4-5 working days but that was it had said, it will. No hidden charges I paid to any party. I got an exchange rate of 39.75, when that day's exchange rate was ~40.1. Not that bad. When I initiated the transaction, it showed me an exchange rate of 39.30. But the day transaction actually happened at the backend, Re had become weeker to $. I got 39.75. That probably means, the exchange rate you get could be lower or higher than what it shows to you at the time of transfer, depending on how the currency rate goes during those first 1-2 days.
