Car-Sharing Points | Membership Sign-up Cases + Usage-Fee Payment Cashback

Car-sharing services like Times Car, Careco and Mitsui's Car Share are a genre where membership sign-up (joining) is sometimes a point-site sign-up case. Pay the monthly and usage fees with a cashback-earning method, and you save a little every time you drive. The trick: route the sign-up application through a point site, check the case conditions (sign-up only, or is a first use required?), pay monthly/usage fees with a cashback method, and use rentals instead for short trips when cheaper. For people who don't own a car and drive only when needed, you can grab both the sign-up case and ongoing payment cashback. This article organizes car-sharing points. See also Rental Cars, Gasoline, and Cars (general).

💡

The core of car-sharing points is "grabbing both the routed cashback on sign-up (a sign-up case) and the payment cashback on monthly/usage fees." If your style is not owning a car and driving only when needed, take the case at sign-up and then stack payment cashback each time you drive. But choosing a service/plan that fits how you drive comes first. Whether there's a monthly fee, the number of nearby stations (pickup spots), and the fee structure differ by service, so judge by whether it's convenient in your area. Signing up for a service you won't use just for cashback can leave you paying only the monthly fee — a loss. For short trips, compare with rentals and pick the cheaper.

Things to note

  • Pick a service/plan that fits how you drive: Whether there's a monthly fee, the number of nearby stations, and the fee structure differ by service. Choose by whether it's convenient in your area; don't sign up for a service you won't use just for cashback.
  • Check earning conditions: "Joining only," "first use required" differ by case. Miss the conditions and you earn zero. Check before applying. Pointnavi.
  • Don't forget to route: A sign-up application earns zero cashback if you skip the point site. Always route before applying.
  • Mind monthly fee & cancellation / pool points: A monthly fee may apply even in periods you don't drive, so consider canceling if your usage is low. Pool awarded points into your main ecosystem and use them before they expire. Avoiding Expiry.
