Why are you saying my PayPal account may already be in use?
Please don't worry: nobody else is using your PayPal account. Sometimes a second Spare5 account is accidentally created, but that's very easy for us to fix.
Please write to us at email@example.com with the correct email address(es) for your Spare5 account and the Paypal account.
