There is no limit to the amount of Karshare Credits you can earn through renting cars with us and referring friends. If you have accumulated £50 in Credits, and your next booking is worth £50, you will get that booking for free.
There is, however, an expiry date on Credits. Unused Karshare Credits will expire after 12 months from the date you earned the Credit. You can keep an eye on your Karshare Credits in your account information.
