Amex is out with a new targeted Amex Offer for Silvercar car rental: Spend $500, Get $100 Back.
Spend $500 or more with Silvercar, in one or more transactions, and get $100 back. Expires 10/6/21.
With many car rental companies struggling to provide enough rental cars for the surge in demand domestically, Silvercar might be a good alternative. It’s not cheap, but it’s much better than arriving at a car rental shop and finding that they are sold out of cars (assuming that doesn’t happen with Silvercar — I don’t know this to be the case one way or the other).
