I have 10k tatacliq voucher got for magnus, + i earned 5k tatacliq voucher from cheq app. Now total i have 15k card balance in tatacliq wallet. I am looking to use it in a best way to convert it into cash with out loosing much or buying some perfumes etc.... But the perfumes which i wanted are not there on tatacliq website, therefore i am wanting to convert this 15k amount to cash by purchasing gold coin etc.... If i buy gold, which one would be better so that i don't have to loose much amount at teh time of selling in market at jwelry shop?
