What I have done in past . I buy Kalyan gold coin vouchers using Amazon pay and Amazon shopping vouchers.these vouchers are valid for 1 year from date of purchase and then buy gold from it before diwali.
I think of them as investment and considering physical gold has 3% gst still it comes out to be net positive. (We can argue against this investment instrument as sgb gives 2.5% interest for 8 years, so this is kind of total 6-7% less returns over 8 years but more liquidity)
Now that it's spoken I am sure this option will go away 🤣🤣🤣
