Personal Shell Card Anyone?

[Wui75]

Any Personal Shell Card holder here?

 

I need to know whether this card is worth to get. I was totally confused by the website saying that there is 6% discount when using this card, and then there was another webpage saying that the additional 3% discount will be extended. Does these discount apply to the price board listed outside Shell stations, or the discount is already inclusive of the station discount, meaning that total will be 6% or 9% off the actual pump price?

 

Right now I am using UOB Platinium Card to get additional 5% discount.
