Amazon partners with several credit card providers to offer discounts when you use a minimum number of reward points to pay for part of your purchase. Note that these offers are targeted, so not everyone will be eligible, but it's worth checking to see if you have the offers on your account.
American Express: Check this page to see if you're targeted. Offers can vary from 10% to 50% off. Common offers are 10% off up to $10 and 15% off up to $15.
Chase: Check this page to see if you're targeted. Again, current offers vary. Several reports of 50% off, up to $15 in savings but your offer may be different.
Capital One: Check this page to see if you're targeted. The most frequent offer is 40% off with a maximum discount of $20, but these can also vary.
Discover: Check this page to see if you're targeted. The offers vary. Some reported offers are $10 off $50, 30% off up to $30 and 40% off up to $30.
U.S. Bank: Check this page to see if you're targeted. Once again, the offers for those targeted will vary. Maximum discount seems to be 40% for this one.
To be eligible for these offers, you need to link your credit card rewards account to your Amazon account for each card. You can do that on the Shop with Points page. If you've just linked your account, wait 1-2 days and try the links again to see if you get targeted for an offer.
