Need expert option on the below.
I have HDFC infinia and mostly I don't use the max cap of smartbuy bonus points. I am planning to use this to buy Amazon shopping vouchers and use that to buy gold coin vouchers of kalayn/Jos Lukas/PC jeweler from Amazon. The goal is to accumulate gold coins at a discount and use it as exchange while buying jewellery for wife or other family functions.
Here are few of my questions
1. Can Amazon shopping voucher be used to buy gold coin vouchers from Amazon.
2. Which of the these big jewellery chains take less markup (making changes) for buying gold coins and do they provide 100% value during exchange while buying jewellery ?
3. Has anyone done the cost analysis on buying gold coin in this way and whether it is worth the hassle.
Please note that I am not comfortable buying gold coins directly online as I have heard that you don't get proper bills from jewellery shops and that may cause issues while doing the exchange.
Thanks in advance for your help.
