Searched and found a thread about upgrading existing cards from 3% to 5% cash back but nothing about this new card from amazon. I saw it when I logged in as a banner on the front page.
5% cash back at amazon.com (with prime membership - 3% without prime)
2% cash back at restaurants, gas stations, and drugstores
1% cash back everywhere else
no annual fee
no foreign transaction fees
various insurance perks
purchase and warranty protections
complimentary 24/7 visa signature concierge
room upgrades and VIP status at premium properties in the Visa signature luxury hotel collection.
YMMV - some offers only 3% and varying gift cards. possibly need to be logged in as the primary account holder for 5% offer
