i wanted to use, but they din allow..... they also told me the rest of this month also dun think i can use cos now got a 21% promo going on....
The 21% promotion you're referring to is from using the American Express Card?
The upfront discount is 15% (10% SPC&U Membership Discount + 5% American Express Card Discount) and 7.1% American Express Card Rebate (effectively 7.1% * 0.85 = 6%), so total
21%.
When there is special promotion like the 23% discount, it overwrites the 15% upfront discount so you get 23% upfront discount + 7.1% American Express Card Rebate (on the outstanding amount payable so effectively 7.1% * 0.77 = 5.46%) =
28.46% discount (as compared to the regular 21%).
Now the question is whether the $5 off $70 physical coupon can be stacked with the 23% promotion. If can, then the optimal amount of petrol to pump is $90.91. ($90.91 * 0.77 - $5) * 0.929 = $60.39 (
33.57% discount). Based on the coupon terms and conditions, I doubt it can stack due to clause 6.
