I had my Amazon Prime subscription auto-renew two months ago. Amazon billed my Discover and I got no special rewards. I now have an offer for 5k MRs for a year's subscription on my Platinum, but the offer expires several months before my scheduled renewal.
Would it be easy to get a refund on my Discover for the remaining 10 months of my current membership? Would there be anything preventing me from immediately rejoining, paying with Platinum?
Or is the $99 on Discover a sunk cost if I want to avoid an interruption of Prime membership for more than a few weeks?
I have used the shipping feature.
One complicating factor is that I have a few video channel subscriptions linked to Prime (which my mother also uses), so cancelling it would mean having to re-enroll in them. So I wouldn't be the only one impacted if there was some lengthy interruption.
I may see if others use the offer in a similar way and have a smooth experience. The offer is good for about 6 months. Other people can be guinea pigs.
Does anyone know of a way to prepay Prime for the 8/2018-8/2019 period?
