Hi sundaram  thank you with that reply , but since i had 2 orders from tower hobbies as i had mentioned before so why is that the order which was shipped on 21 Aug 2014 reached me  in 8 days and the order which i made on 6 Aug 2014 has not reached me till now

How do the USPS people ship i mean do they have the same route to INDIA

Any suggestions why the 1st order has taken so much of time and still not arrived ?

There is always exception. You are lucky that the first one reached in eight days.  Yes sometimes you might get your package earlier than 45 days. But non tracking priority mail it's always safe to expect it later than 45 days

Ok Thank you with that , but that's the second parcel which i got in 8 days not the first one ,first order has still not arrived ,so what i want to ask is  that is this normal   , and i should wait
