I can't use my maestro card in app store!

I have not seen an official Apple statement ... which is why I was careful to write 'I understand'.

I wrote in that way as several senior contributors have written about problems with debit cards and particular reference was made to India. Being unable to ascertain the OP's locality I used the proviso.

The global diversity of Apple's interests does tend to make hard and fast rules difficult to establish and perhaps a less autocratic approach to the occasional deviation might be in order.

Apple has no issues taking personal debit cards issued by banks and directly tied to a user's demand deposit accounts in the bank. The iTunes/Mac App Store system handles them equally as credit cards. It is because these are verifiable with the issuing banks, and have verifiable billing addresses that show that the user is domiciled in the country.

Apple has never taken pre-purchased, self-funded debit cards, regardless of the mark; VISA, MasterCard, etc.

I m using itunes 11 on my laptop and there are 2 options only namely visa and master card no other options are there what can i do

If you don't have a VISA or MasterCard then you will have to use iTunes Gift Cards. Perhaps you can buy them with the card that you have in a local store.
