In the Gift cards section, there are two types of Amazon gift cards. One with 2% discount and other without any discount.
It turns out that the one with 2% discount are infact Amazon Vouchers (can be used only for shopping and not for other stuff like bill payments, outside merchants who accept amazon pay etc.) and not Amazon Gift cards.
This Amazon Vouchers seems to be a new concept launched recently by Amazon and most don’t know about it.
I realized it after buying the gift card from Jupiter and after adding to Amazon when it was not added to my Amazon pay balance.
So, please clearly mention on the respective cards in the Gift Cards section in Jupiter app. Currently, there isn’t much difference between them in the Jupiter app.
