Well, there are couple of wyas of getting waiver (as mentioned above). Since you are trying to get milloin worth education, why do you hesitate to spend some money on application fee. Don't think of getting everything free. I spent some while applying for two universities and got fellowship in both and chose one. So, if you think you are deservng candidate, don't waste your time thinking this and that, just chose one or two good universities and apply with whatever fee you have to pay. Good luck!
