I have also used the spark prepaid at a petrol station, getting double points using an amex gold charge card for only around 1.5% of the money churned. As Raffles said before though, you shouldn't go abusing inexperienced staff in small stores as this will put the retailer out of pocket. The chain I used was Texaco and I generally added the transaction to my petrol purchases. Max refil was £250 a time, so not as quick as some methods.
