I applied to the US for admission this year and needless to say I had to send lots of recommendations and tax documents. I don't think everybody knows this but there's a service called the EMS (Express Mail Service) provided by the post office which is a guaranteed service (i.e if the mail is not received you can hold the post office responsible) and will deliver your mail within delivered five days and the cost is very minimal. Documents that cost me about Tk.500 by the EMS would have taken four to five times that amount by DHL or other private courier services. And that would have been absolutely impossible for me to afford. Even the regular foreign mail service is extremely reliable. It will take no more than two weeks to deliver, and that I think is very reasonable for eighty bucks. I would also like to say that not a single of the thirty or forty pieces of documents I have send over the last two months to various states around the US have been missed. Yes, there was a time when I too winced at the sound of the GPO, "What? That old place?" But I stand corrected. GPO, you rock!
