Duplicate Transaction Checking

This setting rejects transactions if another successful transaction has been completed with the same payment method, order ID, and amount within the last X seconds. X can be set to up to 3600, or one hour. This setting is useful if your customer clicks the back button, refreshes the page, or anything else that might cause the transaction to be put through twice. Note: This setting only applies to credit card transactions, not to transactions done through Paypal.

Recommended settings: Enabled; 30 seconds.
