You can pay into the club in two ways;
1. Subscription Payment - as per set in the club using a Visa or MC (or debit card with one of those facilities). OR a Ladbrokes Transfer (from your personal account). You'll see the Subscription Payments option on the Main Menu.
2. Fund club Account - which allows you to pay ad hoc in any amount either by transferring from your Ladbrokes account or via a credit card. Also found in the Main Menu when on the club dashboard.
