Hello Ashsrikar,
Beats me.. as to why..
May be the primary and the derivative cases are getting separated at the card production stage. For a while, I thought, that the stack got divided into 2 and mine got to be the last one in stack 1 and my wife's first in stack 2 and that was the reason why she got it sooner. But, this pattern seems to be repeated.
The other issue that worried me was that my wife's card was sent to our old address, despite my writing and calling-in the address change to VSC. And, to top that, the US Postal service happily forwarded the mail (WHICH FOR INS MAIL THEY ARE NOT SUPPOSED TO DO!!!! ) and we received it at our new address.
Anyway, as long as we receive the card, I think we can be happy.
BTW, if Srikar is your husband's name, did he go to PSG Tech. in Coimbatore? If so, we might know each other.
