When you use Pay & Go to make your purchase you authorise a pre-authorisation hold against your nominated card:

(a) equal to the value of the fill limit you select in ‘Fuel Up’ for fuel purchases; and

(b) equal to the cost of the goods in your basket for Shop In-Store at all stores that do not have a Pay Station,
(each a Pre-authorisation Hold).

For Pay & Go Fuel Up transactions, you may fill up fuel, up to the amount of the Pre-authorisation Hold and you will only be charged for what you fill.

If a Pre-authorisation Hold is not granted for any reason, you will not be able to proceed using Pay & Go and must complete your purchase at the check-out.  If you decide not to complete the transaction after the Pre-authorisation Hold is granted, the Pre-authorisation Hold will remain until your bank releases it.

A Pre-authorisation Hold will be made each time you authorise payment using a nominated card. This may result in multiple Pre-authorisation Holds – for example, if you cancel a payment authorisation, or a payment authorisation times out, and you proceed with another payment authorisation. 7-Eleven is not responsible for, and has no control over, the time it takes for your bank to release a Pre-authorisation Hold (or any part of) or if multiple Pre-Authorisation Holds, result in your bank declining a transaction due to insufficient funds.   Please contact your bank if you have any questions.
