I am going to need to learn this

My mistaks... I once purchased an Amazon egift card through Bitrefill and decided not to use it, and exchanged it back and received Bitrefill rewards for the equivalent value, which I then used to buy sats. Hope that helps (it was last year and I forgot).
Oh I gotcha - yes I have seen bit refill might have a good use case to test next time I need to top up a wallet. Looks like some good options are out there it is just not what I was expecting at all
