which private courier company asked you 500 for sending pan card application :whew:
I have used dtdc, bluedart and few less known companies to deliver packages say upto 100gm or so to mumbai, tamilnadu never had to pay more than 60.
and on topic: bank has sent some docs using registered or speedpost so i don't have a choice,earlier also they messed up my cheque delivery after a lot of complaints it was delivered to me after 2 months which I had to get cancelled and all the time wasted in the mess costed me more than 500
