Not quite as much damage to the Citi Costco Anywhere Visa (likely due to contractual restrictions with Costco) but the price rewind cut still hurts:
Effective September 22, 2019, Trip Cancellation & Interruption Protection and Citi® Price Rewind will be discontinued and will no longer be provided for purchases made on or after that date. Coverage for purchases made before that date will continue to be available, and you may continue to file for benefits in accordance with the current benefit terms.
Much more damage on the Citi Double Cash:
Effective September 22, 2019, Worldwide Car Rental Insurance, Trip Cancellation & Interruption Protection, Worldwide Travel Accident Insurance, Citi® Price Rewind, 90 Day Return Protection, Damage & Theft Purchase Protection, and Extended Warranty will be discontinued and will no longer be provided for purchases made on or after that date. Coverage for purchases made before that date will continue to be available, and you may continue to file for benefits in accordance with the current benefit terms.
