Thanks for the reply.Yes for travel i dont want to use it as i am already using smartbuy hdfc (holding infinia metal).Don't want to use on other international brands as mostly i will buy bags and other accessories from Ajio / Amazon.If tata cliq would have allowed gold coins purchase from gift cards that would be the best bet.I think no one else can answer this question except you. You can select the voucher based on your requirement.
