So used a total of 13 Vouchers?
I'm planning to club 3 quarters. That makes it 24 Vouchers. There's no mention of the maximum number of Vouchers that can be used against a single bill in the T&C, so I'm looking for some reassurance. Emailed tanishq support, they said it's based on the T&Cs of the voucher-seller. HDFC & smartbuy are saying it's determined by Tanishq.
