When you redeem AmEx MR points with "Use Points for Purchases" and "Amazon Shop with Points" before Sep 30, 2020, you can use the special offer redemption rate of 1000 MR = $10 credit. This offer is for almost all AmEx MR credit cards, except AmEx Platinum. I think the best credit card for this offer is AmEx Cobalt.
At the same time, when redeem AmEx MR points for AmEx Prepaid Card, you can use the similar special redemption rates as well.
