YMMV. I got this offer from Amazon/Discover for $10 off a $30 purchase when paying with points. Like previous promotions, you can activate the promo by using as little as $0.01 of Discover Cashback Bonus.
This looks like it's a targeted offer:
Terms and Conditions
This is a limited time offer. The promotion will end on the earlier of (a) 11:59 PT on 9/30/2021, or (b) the time at which offers worth $200,000 have been redeemed. The promotion button will expire concurrently.
Amazon.com reserves the rights to cancel or modify this offer at any time.
Offer is available by invitation only, is non-transferable, is not redeemable for cash, and may not be resold.
Offer applies only to the purchase of at least $30 of eligible products, where Cashback Bonus is used for at least a portion of the purchase and the promotion is activated and applied at checkout.
Offer only applies to products sold by Amazon.com or Amazon.com Services LLC (look for "sold by Amazon.com" or "sold by Amazon.com Services LLC " on the product detail page). Products sold by third-party sellers or other Amazon entities will not qualify for this offer, even if "fulfilled by Amazon.com" or "Prime Eligible".
Offer does not apply to purchase of digital content.
Maximum benefit you may receive from this offer is $10. Limit one promotion discount per Cashback Bonus eligible card. Limit one promotion discount per Amazon.com account.
Offer may not be combined with other offers.
Shipping charges may apply to discounted promotional items.
If any of the products related to your original order are returned, subject to Amazon's refund policy, you will receive a refund of the amount charged to your card first, followed by Cashback Bonus.
Offer discount will be allocated proportionally among all promotional items in your original order. If any of the items in your original order are subsequently returned, your refund will equal the original price of the product, less the proportional amount of the discount. The total discount on the unreturned amount of your original order will then be less than $10.
Promotional codes (including those placed directly in accounts) may not be redeemed for Amazon Gift Cards.
This promotion is available only to Amazon.com customers with a Cashback Bonus card issued in United States.
Promotional discount is applied before taxes and fees.
If you violate any of these terms, the offer will be invalid.
