If you're registering for multiple events, or joining as a member and registering for an event at the same time, you can make a single payment for the multiple transactions. To avoid paying separately for each transaction, follow these steps:
1. For each transaction except the final one, click the "Invoice Me" button rather than the "Pay Online" button.
2. For the final transaction, click the "Pay Online" button and all your transactions will be combined into a single payment.
